Jesus second coming and Imam Mahdi (ficticious character) is so deeply rooted in Sunnis and Shias belief that they reject everything which proves their belief wrong. Jesus is alive is Bibilic belief which creep into Islam through the backdoor of hadiths with the help of persian Imams.

Catholic Christians have always believed that Jesus Christ would come back to close the current period of human history in earth. The time when Jesus will return is given many names the Day of the Lord, the Parousia, the end time, and the Second Coming of Christ.

The Bible describes the events of Jesus' return in apocalyptic images.

Mk 1326-27
And then they will see 'the Son of Man coming in the clouds' with great power and glory, and then he will send out the angels and gather (his) elect from the four winds, from the end of the earth to the end of the sky.

Mt 1627
For the Son of Man will come with his angels in his Father's glory, and then he will repay everyone according to his conduct.

Acts 111
They (two men dressed in white) said, "Men of Galilee, why are you standing there looking at the sky? This Jesus who has been taken up from you into heaven will return in the same way as you have seen him going into heaven."

1 Thess 416-18
For the Lord himself, with a word of command, with the voice of an archangel and with the trumpet of God, will come down from heaven, and the dead in Christ will rise first. Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air. Thus we shall always be with the Lord. Therefore, console one another with these words.
The parousia will be unmistakable because it will be accompanied by unprecedented signs.

Mt 2427
For just as lightning comes from the east and is seen as far as the west, so will the coming of the Son of Man be.
Some signs are general events concerning the evangelization of the world.

Mt 2414
And this gospel of the kingdom will be preached throughout the world as a witness to all nations, and then the end will come.

Other signs are more proximate. Mark (Chapter 13), Matthew (Chapter 24), and Luke (Chapter 21) all describe the unmistakable signs with apocalyptic images.

2 Tim 41-2
I charge you in the presence of God and of Christ Jesus, who will judge the living and the dead, and by his appearing and his kingly power proclaim the word ...

2 Tim 31-5
But understand this there will be terrifying times in the last days. People will be self-centered and lovers of money, proud, haughty, abusive, disobedient to their parents, ungrateful, irreligious, callous, implacable, slanderous, licentious, brutal, hating what is good, traitors, reckless, conceited, lovers of pleasure rather than lovers of God, as they make a pretense of religion but deny its power. Reject them.
No one knows exactly when this will occur.

Mk 1332
(Jesus began his discourse ...) "But of that day or hour, no one knows, neither the angels in heaven, nor the Son, but only the Father."

1 Thess 52
For you yourselves know very well that the day of the Lord will come like a thief at night.

2 Pet 310
But the day of the Lord will come like a thief, and then the heavens will pass away with a mighty roar and the elements will be dissolved by fire, and the earth and everything done on it will be found out.

The Catholic Church teaches that we should avoid pointless speculations about the time, the details of the signs, the nature of the difficulties, etc. The Church focuses instead on the need for living the Gospel so as to be prepared for the parousia whenever it happens.

Mk 1333,35-37
(Jesus began his discourse ...) "Be watchful! Be alert! You do not know when the time will come. ... Watch, therefore; you do not know when the lord of the house is coming, whether in the evening, or at midnight, or at cockcrow, or in the morning. May he not come suddenly and find you sleeping. What I say to you, I say to all 'Watch!'"

1 Pet 113-16
Therefore, gird up the loins of your mind, live soberly, and set your hopes completely on the grace to be brought to you at the revelation of Jesus Christ. Like obedient children, do not act in compliance with the desires of your former ignorance but, as he who called you is holy, be holy yourselves in every aspect of your conduct, for it is written, "Be holy because I (am) holy."

Bukhari hadiths.
Volume 3, Book 34, Number 425

Narrated Abu Huraira
Allah's Apostle said, "By Him in Whose Hands my soul is, son of Mary (Jesus) will shortly descend amongst you people (Muslims) as a just ruler and will break the Cross and kill the pig and abolish the Jizya (a tax taken from the non-Muslims, who are in the protection, of the Muslim government). Then there will be abundance of money and no-body will accept charitable gifts.

What a senseless story? Break the cross and kill the pig. Hilarous and illogical.

Volume 3, Book 43, Number 656
Narrated Abu Huraira
Allah's Apostle said, "The Hour will not be established until the son of Mary (i.e. Jesus) descends amongst you as a just ruler, he will break the cross, kill the pigs, and abolish the Jizya tax. Money will be in abundance so that nobody will accept it (as charitable gifts).

How Jesus will become the ruler is not explained in these stories. How Jesus will fight Christians with so much of nuclear weapons power and technology?

Volume 4, Book 55, Number 568
Narrated Ibn Abbas
The Prophet said, "You will be gathered (on the Day of Judgment), bare-footed, naked and not circumcised." He then recited--'As We began the first creation, We, shall repeat it A Promise We have undertaken Truly we shall do it.' (21.104) He added, "The first to be dressed on the Day of Resurrection, will be Abraham, and some of my companions will be taken towards the left side (i.e. to the (Hell) Fire), and I will say 'My companions! My companions!' It will be said 'They renegade from Islam after you left them.' Then I will say as the Pious slave of Allah (i.e. Jesus) said. 'And I was a witness Over them while I dwelt amongst them. When You took me up You were the Watcher over them, And You are a witness to all things. If You punish them. They are Your slaves And if You forgive them, Verily you, only You are the All-Mighty, the All-Wise." (5.120-121)

Wrong interpretation of Qur'an verse given here in this hadith by this wordly god of Sunnis. Jesus is not alive sitting with God Almighty and watching us all.

The following two verses explain clearly Allah Subhan Wa Taala message.

5116 And behold! God will say "O Jesus the son of Mary! Didst thou say unto men, worship me and my mother as gods in derogation of God'?" He will say "Glory to Thee! never could I say what I had no right (to say). Had I said such a thing, thou wouldst indeed have known it. Thou knowest what is in my heart, Thou I know not what is in Thine. For Thou knowest in full all that is hidden.

5117 "Never said I to them aught except what Thou didst command me to say, to wit, 'worship God, my Lord and your Lord'; and I was a witness over them whilst I dwelt amongst them; when Thou didst take me up Thou wast the Watcher over them, and Thou art a witness to all things.

Bukhari according to my analysis did never read the Qur'an himself and he had no knowledge about the message. These two verses are self explanatory do not need any further clarifications.

Shias Version of Hadiths
"Al Mahdi is from my progeny. His name is the same as my name. And his kunniyat is the same as my kunniyat. In his physique and character he looks exactly like me. He will be in a state of occultation and there will be confusion (Hayra) in which people will wander about (deviate). Then he will come forth like a sharpy shooting star to fill the earth will justice and equity as it was filled before with injustice and inequity."

(Kamaaluddin Vol.1 Pg.286. Faraidus Simtain Vol.2 Pg.335)
"Al Mahdi is from my progeny. His name is the same as my name. And his kunniyat is the same as my kunniyat. In his physique and character he looks exactly like me. He will be in a state of occultation and there will be confusion (Hayra) in which people will wander about (deviate). Then he will come forth like a sharpy shooting star to fill the earth will justice and equity as it was filled before with injustice and inequity."

(Kamaaluddin Vol.1 Pg.286. Faraidus Simtain Vol.2 Pg.335)
"Verily each of my ancestors had the oath of allegience, upon their necks, of their contemporary tyrant rulers. But I will reappear at such a time that I will not have any tyrant's allegience upon my neck."

(Ghaibat Tusi Pg.292, Kamaaluddin VoL2. Pg.485)
"The Qaem is the one who will purify the earth from the enemies of Allah, the High and the Mighty. And he will fill the earth will justice and equity just as it is filled with injustice and tyranny. He is the fifth of my descendants. He will go into occultation due to the fear of his own (life)."

(Kamaaluddin vol.2 Pg.361. Kifayatul Asar Pg.265-266)
Imam Mahdi (A.S.) said.

"If our shias; may Allah help them in His obedience; would have fulfilled their covenant with united hearts then there would have. been no delay in our meeting, and they would have been blessed with our visitation at the earliest, along with the recognition of truth and confirmation of our rights."

(Al Ihtejaj vol.2 Pg.602)
The Holy Prophet (S.A.W.S.) said,
"The best worship is to await for the reappearance."
(Kamaaluddin vol.1 Pg.287, Faraidus Simtain vol.2 Pg.335)

These can't be the words of our Prophet Muhammad as they are clear contradiction to Qur'an and against the Laws Of Allah Subhan Wa Taala.
Amirul Momineen Ali (A.S.) said,
"Await for the reappearance and do not despair of the divine mercy. Because the best deed in the eyes of Allah, the Great and the Mighty is to wait for the Reappearance. It is the duty of those who are believers."

(Al Khisaal vol.2 Pg.616)
Imam as-Sajjad (A.S.) said.

"The greatest success is to wait for the reappearance"
(Al Ihtejaj vol.2 Pg.154. Kamaaluddin vol.1 Pg.320)
Imam Jafar as-Sadiq (A.S.) said,

"Those of you who die on this affair (shia faith) while you are in a condition of awaiting, are like those who has served the Qaem (A.S.) in his tent."
(Ghaibat-e-Nomani Pg.200)
Imam Al-Jawad (A.S.) said,

"Certainly the Qaem from among us is the Mahdi. Awaiting for whom is obligatory during (his) ghaibat and obeying him is obligatory after his reappearance. And he is the third of my descendants."
(Kamaaluadw vol.2 Pg.377)
Imam as Sadiq (A.S.) said,

"One who desires to be among the companions of the Qaem, must await, adopt piety and behave courteously. If he dies in such a condition before the advent of Qaem, then his reward will be similar to the one who attains his era. Hence, congratulations to you all for your relentless awaiting."

(Ghaibat-e-Nomani Pg.200)
Hazrat Imam Baqir(A.S.) explains the tafseer of this ayat

"Have patience in fulfilling the religious obligations, Excel in patience in facing your enemies. And be in contact with your Imam who is awaited".
(Ghaibat-e-Nomani. pg.27, Yanabiul Mawadda pg.421)

How to be in contact with the Imam who do not really exist? Mahdi is ficticious character created by persian Imams. This was the deliberate efforts of these persian Imams to make muslims a dead nation leaving them with dreams of everything will be fine when Mahdi will emerge without any struggle against Mongoanlians and cause a permenant division amoung muslims.

"Al Mahdi is the one who will fill the earth with justice and equity just like it had been filled with injustice and tyranny. I swear by the one who has sent me as the giver of good tidings, even is a single day remains for the world (to end), Allah shall prolong that day till he sends (to it) my son Mahdi. Then Ruhullah (spirit) Isa ibne Maryam will descend and perform prayers behind him. The earth shall be illuminated by his radiance and his authority shall stretch from the east to the west."

(Faraidus Simtam vol.2 Pg.312)
"If he would be recognized then he would be reduced to bits and pieces."
(Ghaihat e Tusi, pg. 333; Beharul Anwar, Vol. . 52,pg.9

Why Mahdi is so scared of death? Dying for the cause of Allah Subhan Wa Taala is the biggest achievement for all human. Mahdi do not have to hide and be scared of death as according to these hadiths he possess the power of Almighty (God fogive me for writing this) according to these hadiths.

Zoroastrian Belief.

Faith, and Hope in the coming of the Saoshyant (Saviour) has sustained our religion through the centuries. We firmly hope, and pray, that Ahura Mazda sends the Saoshyant to the earth to defeat evil and further righteousness (Ashoi). The Zarathushtri religion was the first to proclaim that Ahura Mazda will send the Saoshyant, born of a virgin, and many other religions took on this belief.
We firmly believe that when the Saoshyant comes, the final spiritual battle between the forces of good and evil will commence, resulting in the utter destruction of evil. Ristakhiz, the ressurection of the dead will take place - the dead will rise, by the Will of Ahura Mazda. The world will be purged by molten metal, in which the righteous will wade as if through warm milk, and the evil will be scalded. The Final Judgement of all souls will commence, at the hands of Ahura Mazda the Judge (Davar), and all sinners punished, then forgiven, and humanity made immortal and free from hunger, thirst, poverty, old age, disease and death. The World will be made perfect once again, as it was before the onslaught of the evil one. Such is the Frashogad (Frasho-kereti), the Renovation, brought on by the Will of Ahura Mazda, the Frashogar. .... Zoroastrian belief.....

The muslims believe that Jesus will come back to earth along with Mahdi to fight the evil and break the cross and than Islam will prevail all over the world and everybody will become Muslim. Zoroastrian belief was modified by persian Imams intelligentlly including as essential part of faith. I cannot openly say that Jesus is dead or Mahdi is a factitious character in any muslim country as I will be instantly murdered or put to death according to corrupt Shariah writen by these persian Imams.

We believe that Jesus, true God and true man, who rose from death and ascended to the right hand of the Father, will come again. He will return visibly, in the same way as his disciples saw him go into heaven (Acts 111).

We believe that no one can know the exact time of Jesus' return. This knowledge is hidden even from the angels in heaven (Matthew 2436). Nevertheless, our Lord has given signs to his believers to keep them in constant expectation of his return (Matthew 244-14). He has told them to be alert and to watch so that day will not come upon them unexpectedly (Luke 2134). More Christian belief....

"Whenever there is decay of righteousness... and there is exaltation of unrighteousness, then I Myself come forth... for the destruction of evil-doers, for the sake of firmly establishing righteousness, I am born from age to age." --- KRISHNA- Bhagavad Gita- fourth discourse. Hinduism belief....

'I am not the first Buddha Who came upon this earth, nor shall I be the last. In due time another Buddha will arise in the world, a Holy One, a supremely enlightened One, endowed with wisdom in conduct, auspicious knowing the universe, an incomparable leader of men, a Master of angels and mortals. He will reveal to you the same eternal truths which I have taught you. He will preach to you His religion, glorious in its origin, glorious at the climax and glorious at the goal, in spirit and in the letter. He will proclaim a religious life, wholly perfect and pure, such as I now proclaim.' His disciples will number many thousands, while Mine number many hundreds.' Budhist belief...

Shias put a curse on me after reading this, Sunnis do not consider me muslim, Ahmedis hate me like hell. Shias radical organization might me searching for me to fulfill their religious duty of killing a kafir like me.

The information is open for all to search and follow the right path instead of following conjecture and following what their forefathers were following blindly.
