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."
In one narration the wording is: "And does not believe in me, he will not enter Paradise."
Al-Tabarani recorded it, and these are his words; Imam Ahmad recorded something similar in both narrations, and Imam Ahmad's narrators are those of the Sahih; al-Bazzar also recorded it in abridged form.
Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "By the One in whose Hand is the soul of Muhammad (peace and blessings be upon him), whoever of this Ummah hears of me, or any Jew or Christian who hears of me, and dies in a state in which he has not believed in what I have been sent with, that person will be among the people of Hell." (Allamah al-Haythami says:) I say: This report is mentioned in the Sahih, and its wording is: "Whoever of this Ummah, Jew or Christian, hears of me."
Imam Ahmad recorded it, and its narrators are the narrators of the Sahih.
