مسند أحمد

It was narrated from ‘Ubaidullah bin Abi Rafi’, the freed slave of the Messenger of Allah (ﷺ) , from `Ali bin Abi Talib (رضي الله عنه) that The Messenger of Allah (ﷺ) stood in Arafah with Usamah bin Zaid riding behind him, and said: `This is the place of standing, and all of `Arafah is a place of standing.` Then he moved on at an unhurried pace, and the people started rushing right and left. He turned to them and said: `Calmly, O people; calmly, O people.” Then he came to al-Muzdalifah and put two prayers together, then he stood in al-Muzdalifah in a place called Quzah, with al-Fadl bin al-`Abbas riding behind him, and he said: “This is the place of standing and all of Muzdalifah is a place of standing.” Then he moved on at an unhurried pace and the people started rushing right and left. He turned to them and said: `Calmly, O people; calmly, O people.” he quoted the hadeeth at length.
