How can I show my brother the clear proofs of Islam? I'm worried he might leave the deen.
Salam alaikum, everyone. There's a Muslim guy at my school who's thinking about Christianity, and it really troubles my heart. I used to be Christian, but alhamdulillah, I found Islam and left it behind. I shared my reasons with him-like how the Trinity never sat right with me and how the many Christian sects all disagree with each other. Masha'Allah, he actually listened and seemed open to my points. Now I need your help: please share any Quranic ayahs, authentic hadiths, or scientific facts that match what Islam teaches-anything that can help keep him on the straight path. Jazakum Allahu khayran.
