It was narrated from Abu Rafi’ that Umar bin al-Khattab was leaning on Ibn ‘Abbas, and Ibn 'Umar and Sa'eed bin Zaid were with him. He said: You should note that I have not said anything about kalalah and I have not appointed anyone to succeed me. Whoever of Arab captives are present when I die, are to be freed although they are among the wealth of Allah, may He be glorified and exalted. Sa'eed bin Zaid said: Why don't you suggest a man among the Muslims so that the people may follow your advice? Abu Bakr did that and the people followed his advice and trusted him. ‘Umar said: I have noticed too much greed and ambition, and I will leave this matter to be decided by these six people with whom the Messenger of Allah ﷺ was pleased when he died. Then ‘Umar said: If one of the two men were still alive, I would have referred to this matter to him and I would have trusted him: Salim the freed slave of Abu Hudhaifah and Abu 'Ubaidah bin al-Jarrah.
