مُسْنَدُ أَحْمَدَ
Musnad Ahmad 2648
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn ‘Abbas (رضي الله عنه) said: The Messenger of Allah (ﷺ) did ‘Umrah during the Hajj season until he died, as did Abu Bakr until he died, and 'Umar until he died, and 'Uthman until he died. The first one to ban that was Mu'awiyah. Ibn 'Abbas said: I was surprised at that, as he had told me that he cut the hair of the Messenger of Allah (ﷺ) with the head of an arrow.
