Musnad Ahmad 2495
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn 'Abbas (رضي الله عنه) said: I saw the Prophet standing in ‘Arafat, with al-Fadl seated behind him on his mount. A Bedouin came and stood nearby, with a slave woman behind him, and al-Fadl started looking at her. The Messenger of Allah (ﷺ) noticed that, and started turning his face away, Then he said: "O people, it is not righteousness to move quickly with camels and horses; you should be calm." Then he moved on, and I never saw any camel raising its feet and running, until he came to Muzdalifah. When he halted in Muzdalifah, he seated Usamah behind him on his mount, then he said: "O people, it is not righteousness to move quickly with camels and horses; you should be calm.” Then he moved on, and I never saw any camel raising its feet and running, until he came to Mina. And we came with a multitude of the weak of Banu Hashim on donkeys of theirs, and he started patting our thighs and saying: "O my sons, move on, but do not stone the Jamrah until the sun rises."
