Sahih Muslim — Hadith #7595

Narrated by Ishaq ibn Mansur, who said: Mu'adh ibn Hisham told us, who said: My father told me, on the authority of Qatadah, who said: Anas ibn Malik told us that the Prophet of Allah (peace and blessings be upon him) and Mu'adh ibn Jabal were riding together on the mount. The Prophet said, "O Mu'adh!" Mu'adh replied, "At your service, O Messenger of Allah, and may you be happy." The Prophet said, "O Mu'adh!" Mu'adh replied, "At your service, O Messenger of Allah, and may you be happy." The Prophet said, "O Mu'adh!" He replied, "At your service, O Messenger of Allah, and at your pleasure." He said, "There is no servant who testifies that there is no god but Allah and that Muhammad is His servant and Messenger, except that Allah will forbid him from the Fire." He said, "O Messenger of Allah, should I not inform the people of this so that they may rejoice?" He said, "Then they will rely on it." So Mu'adh informed them of it at the time of his death, fearing sin.
