Correct me if i am wrong but wasnt the first Quran alone followers started in 1970's? what about all the rest of the Muslims before the 1970's who knew nothing about the Quran only way will they be punished in the hereafter?

Can any of you show me from the Quran the following

1. How many times to pray a day
2. How to pray
3. How much charity to pay

Thanks

Salamu alaykum

Im hoping to get some help by posting this message here.

I want to ask Allah to guide me to the straight path. By doing some research i have come to the conclusion that the correct Islam is either Ahl Sunnah wal Jammah or Quran Only.

I desperately need Allah to help me with this deccision i feel as if im believing more and more in the Quran only way but i do not know if it is Allah giving me these thoughts or the Shaytan!

Is there anything i can recite from the Quran or any dua that i can do to ask Allah to sincerly guide me?

I would like to spend the rest of my life calling to Islam and refuting the claims of the non muslims who fabricate and lie about Islam! but to do this i really need Allahs help first to guide me to the straight path, How do i go about doing this?

Thankyou
