Mu'jam Kabir Tabarani 306 — the people of Kufah complained

It is narrated from Sayyiduna Jabir bin Samurah (may Allah be pleased with him) that the people of Kufah complained about Sayyiduna Sa'd (may Allah be pleased with him) to Sayyiduna Umar (may Allah be pleased with him), so he sent some men to inquire about him in Kufah. Whichever mosque of the people of Kufah they went to, the people only praised him and spoke well of him, until they reached one of the mosques of Banu Abs. There a man called Abu Sa'dah stood up and said: Since you have asked us by Allah, the truth is that he did not go out with the army himself, he did not judge justly, and he did not distribute wealth equally. So Sa'd said: "O Allah! If he is lying, then blind his sight, prolong his poverty, and expose him to trials." Abd al-Malik said: I saw him molesting slave girls in the streets, and when people asked him: O Abu Sa'dah! How are you? he would say: Old, blind, poor and afflicted with trial; the supplication of Sa'd struck me. Imam al-Tabarani (may Allah have mercy on him) said: Abu Sa'dah is the grandfather of Abu Bakr bin Abi Shaybah.
