ʿUthman ؓ went to Makkah for Hajj. The wife of Muhammad bin Jaʿfar bin Abi Talib entered upon him (i.e., her husband) and he spent the night with her. Then the next morning, he (i.e., Muhammad bin Jaʿfar) came out smelling of perfume and wearing a wrapper saturated with safflower dye. He caught up with the people in weariness before they set out. When ʿUthman saw him, he rebuked him and expressed disapproval, saying: Are you wearing something dyed with safflower when the Messenger of Allah ﷺ forbade that? ʿAli bin Abi Talib ؓ said to him: The Messenger of Allah ﷺ did not forbid it to him or you; he only forbade it to me.
