Sahih al-Bukhari Book 77, Hadith 181
When the Prophet (ﷺ) arrived at Mecca, the children of Bani `Abdul Muttalib received him. He then
mounted one of them in front of him and the other behind him.
Allah's Messenger (ﷺ) rode a donkey saddled with a saddle covered with a Fadakiyya velvet sheet, and he made me ride behind him.
The worst of three (persons riding one, animal) was mentioned in `Ikrima's presence `Ikrima said, "Ibn `Abbas said, '(In the year of the conquest of Mecca) the Prophet (ﷺ) came and mounted Qutham in front of him and Al-Fadl behind him, or Qutham behind him and Al-Fadl in front of him.' Now which of them was the worst off and which was the best?"
