A--- Allah the Almighty says in His Glorious Qur'an, {O you who believe! Believe in Allah, and His Messenger (Muhammad (Peace be upon him)), and the Book (the Qur'an) which He has sent down to His Messenger, and the Scripture which He sent down to those before (him)}. (An-Nisa', 136) Allah says: {Say (O Muslims), "We believe in Allah and that which has been sent down to us and that which has been sent down to Ibrahim (Abraham), Isma`il (Ishmael), Ishaq (Isaac), Ya'qub (Jacob), and to Al-Asbat [the offspring of the twelve sons of Ya`qub (Jacob)], and that which has been given to Musa (Moses)

and `Isa (Jesus), and that which has been given to the Prophets from their Lord. We make no distinction between any of them, and to Him we have submitted (in Islam)}.(AI-Baqarah, 136)

Allah says: (Say: I believe in whatsoever Allah has sent down of the Book [all the holy Books, - this Qur'an and the Books of the old from the Taurat (Torah), or the Injeel (Gospel) or the Pages of Ibrahim (Abraham)]}. (Ash-Shura, 15)
