I did ‘Umrah with ‘Ali bin Abi Talib (رضي الله عنه) at the time of "Umar - or at the time of "Uthman. He stayed with his sister Umm Hani" bint Abi Talib, and when he had finished his ‘Umrah he went back, and water was prepared for him and he washed himself. When he had finished washing himself, some of the people of Iraq entered upon him and said: O, Abu Hasan, we have come to you to ask you about something we would like you to tell us about, He said: I think Al-Mugheerah bin Shu"bah is telling you that he was the last of the people to speak to the Messenger of Allah (ﷺ). They said: Yes, we have come to ask you about that. He said: The last of the people to speak to the Messenger of Allah (ﷺ) was Qutham bin al-Abbas.
