Sayyiduna Abu Musa (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever of this Ummah, or any Jew or any Christian, hears of me and does not believe in me will be among the people of Hell." The narrator says: I thought: whatever the Prophet (peace and blessings be upon him) says is also in the Book of Allah. I read the Qur'an and found this verse in it: "And whoever of the factions disbelieves in him, the Fire is his promised place."
