Sayyiduna Harmalah (may Allah be pleased with him) narrates: I came to the Prophet (peace and blessings be upon him) with the delegation of my tribe. He led us in the morning prayer, and when he concluded with salam, I looked at the face of the man beside me but, because of the darkness, I could not recognise him. I said to the Prophet (peace and blessings be upon him): O Messenger of Allah! Give me some counsel. The Prophet (peace and blessings be upon him) said: Keep fearing Allah Almighty; and if you are among some people and you hear them saying about you something that pleases you, then do it; and if you hear them saying about you something you dislike, then leave it.
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir as a narration of Dirghamah bin Ulayyah bin Harmalah from his father, from his grandfather. Ibn Abi Hatim mentioned him with what we have mentioned here and did not refute it. The remaining narrators of this report have been declared trustworthy, and Ibn Hibban mentioned both narrators, Dirghamah and Harmalah, in the book "al-Thiqat".
