Go to your people and say that the Messenger of Allah (ﷺ) says: Ghifar (is a tribe) to whom Allah granted pardon, and Aslam (is the tribe) to whom Allah granted safety.
Sahih Muslim Book 44, Hadith 258
← Previous Hadith I set out along with Jabrir b. 'Abdullah al-Bajali on a journey and he used to serve me. I said to him: Don't do that. Thereupon he said: I have seen Ansar doing this with Allah's Messenger (ﷺ). I swore by Allah whenever I accompany any one of the Ansar, I would serve him and Ibn Muthanni, and Ibn Bashshir made this addition in their narrations: Jarir was older than Anas, and Ibn Bashshir said: He was of a more advanced age as compared with Anas. Allah's Apostle (ﷺ) invoked blessings for the tribes of Ghifar and Aslam.
