You might wanna first read these
7185 Have they not looked at the dominion of the heavens and the earth, and all that God has created? Perhaps their time is drawing near; so in which narrative after this one will they believe?
6112 And as such, We have permitted the enemies of every prophet mankind and Jinn devils to inspire each other with fancy words in order to deceive. Had your Lord willed, they would not have done it. You shall disregard them and their fabrications.
6113 That is so the hearts of those who do not believe in the Hereafter will listen to it, and they will accept it, and they will take of it what they will.
6114 Shall I seek other than God as a judge when He has sent down to you the Book fully detailed? Those to whom We have given the Book know it is sent down from your Lord with the truth; so do not be of those who have doubt.
6115 And the word of your Lord has been completed with truth and justice; there is no changing His words. He is the Hearer, the Knower.
6116 And if you obey most of those on the earth they will lead you away from the path of God; that is because they follow conjecture, and that is because they only guess.
316 And from the people, there are those who will purchase a baseless narrative with which to mislead from the path of God without knowledge, and to make it a mockery. These will have a humiliating retribution.
3923 God has sent down the best narrative, a Book that is similar, dual. The skins of those who are concerned towards their Lord shiver from it, then their skins and their hearts soften up to the remembrance of God. Such is the guidance of God; He guides with it whoever He wills. And for whoever God misguides, then none can guide him.
456 These are the revelations of God, We recite them to you with the truth. So, in which narrative after God and His revelations do they believe?
5234 Let them produce a narrative like this, if they are truthful.
6844 Therefore, let Me deal with those who reject this narrative; We will entice them from where they do not perceive.
6940 This is the utterance of an honorable messenger.
6941 It is not the utterance of a poet; rarely do you believe.
6942 Nor the utterance of a soothsayer; rarely do you take heed.
6943 A revelation from the Lord of the worlds.
6944 And had he attributed anything falsely to Us.
6945 We would have seized him by the right.
6946 Then, We would have severed his life-line.
6947 None of you would be able to prevent it.
7750 So in what narrative, after it, will they believe?
These are just some of the arguments that might be useful in the debate with a sunni or shia. Keep in mind that you must be patient and always grateful to God.
Always seek God and ask Him, He hears all and sees all.
Keep up the prayers sister and read The Qur'an.
Peace.
