Musnad Ahmad #914

It was narrated that ‘Abdur-Rahman bin Abi Laila said: l saw ‘Ali (رضي الله عنه) in ar-Rahbah, adjuring the people, (saying): I adjure by Allah anyone who heard the Messenger of Allah (ﷺ) say on the day of Ghadeer Khumm:`If I am a person`s mowla (friend and supporter) then ‘Ali is also his mawla”, to stand up and testify. ‘Abdur-Rahman said: And twelve men who had been at Badr stood up. It is as if I can see one of them. And they said: We bear witness that we heard the Messenger of Allah (ﷺ) say on the day of Ghadeer Khumm; `Am I not closer to the believers than their own selves and my wives are their mothers?` We said: Yes indeed, O Messenger of Allah (ﷺ). He said: `If I am a person`s mawla (friend and supporter) then `Ali is also his mawla; O Allah, take as friends those who take him as a friend, and take as enemies those who take him as an enemy.”
