Beliefs concerning heavenly books

Allah Ta’ala has sent down many small and large books through the angel Jibra’eel alayhis salaam to the prophets so that they may teach the matters of Deen to their respective communities. Among these books, four are very famous: the Torah which was sent to Musa alayhis salaam, the Zabur which was sent to Daud alayhis salaam, the Injil which was sent to Isa alayhis salaam, and the Quran which was sent to our Prophet Muhammad sallallahu alayhi wa sallam. The Quran is the last of the books. Now, no new book will be sent from the heavens. The instructions of the Quran will remain valid right until the day of qiyaamah. Misguided people changed a lot of things in the other books. But Allah Ta’ala has promised the protection of the Quran. No one can change it in any way.
