Ibn 'Abbas said, "When 'Umar, may Allah be pleased with him, was attacked, I was one of those who carried him into his house. He said to me, 'Nephew, go see who wounded me and who was wounded with me.' I went and returned to tell him, but the room was full at that time. I did not want to step over people's necks because I was young, and so I sat down. 'Umar's rule when he sent someone for a need was that he commanded him not to tell about it. 'Umar had a cover over him. Ka'b came and said, 'By Allah, if the Amir al-Mu'minin makes supplication, Allah will let him remain alive and restore him to this community until he does such-and-such and such-and-such for them' until Ka'b mentioned the hypocrites. He actually named them and used their kunyas. I said, 'Shall I convey to him what you have said?' Ka'b said, 'I only said it because I intended that it be done.' I plucked up courage and stood up, I stepped over people's necks until I sat by 'Umar's head. I said, 'You sent me to find out such-and-such. Thirteen people were wounded with you. Kulayb ibn al-Jazzar was wounded while he was doing wudu' from the cistern. Ka'b swore such-and-such by Allah.' He said, 'Summon Ka'b.' He was summoned and 'Umar asked, 'What did you say?' He replied, 'I said such-and-such.' He said, 'No, by Prophet, I will not make supplication. 'Umar will be wretched if Allah does not forgive him.'"
