Imam al-Hasan al-Basri (may Allah have mercy on him) relates: I heard Sayyiduna Mu'awiyah (may Allah be pleased with him) delivering a sermon, and he was saying: One day I poured water for the ablution of the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) raised his head towards me and said: "Listen! You will be in charge of the affairs of my Ummah after me. So when that happens, accept from those of them who do good, and overlook those of them who do wrong." Sayyiduna Mu'awiyah (may Allah be pleased with him) said: "So I kept hoping for it until I came to stand in this place of mine today."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated it from Ghalib al-Qattan except Yahya bin Ghalib bin Rashid."
