It is narrated from Hasan that Ahnaf said: Once I was performing Tawaf of the Ka'bah when a man from Banu Salim came and met me and said: Shall I give you glad tidings? I said: Yes, certainly, please tell me. He said: Do you remember when the Messenger of Allah (peace and blessings be upon him) sent me to your tribe, Banu Sa'd, so that I may invite them to Islam, you said on that occasion: By Allah! This Messenger has only spoken good, and I have also heard only good about him. When I returned and informed the Prophet (peace and blessings be upon him) of your words, he prayed thus: O Allah! Forgive Ahnaf. He (Ahnaf) said: So, I have the greatest hope in this very supplication.
