Musnad Ahmad 776
It was narrated that Habbah bin al-`Urani said:
I saw `Ali (رضي الله عنه) smiling on the minbar and I never saw him smile more than that, [so broadly that] his eyeteeth appeared. Then he said: I remember what Abu Talib said. Abu Talib came to us when I was with the Messenger of Allah (ﷺ) and we were praying in Batn Nakhlah. He said: What are you two doing. O son of mу brother? The Messenger of Allah (ﷺ) called him to Islam, but he said: There is nothing wrong with what you are doing (or saying), but by Allah you will never get my buttocks higher than me. And [`Ali] smiled in amazement at what his father said. Then he said: O Allah. I do not know that there is a slave of Yours in this nation who worshipped You before me except Your Prophet - and he said it three times. [Then he said:] I prayed seven years before the people prayed
