Musnad Ahmad 2066

It was narrated that Ibn 'Abbas said: When the Messenger of Allah (ﷺ) passed by Wadi 'Usfan, when he went for Hajj, he said: "O Abu Bakr, what wadi is this?” He said: Wadi 'Usfan. He said: “Hood and Salih passed through it on red camels, with reins of palm fibres. Their izars were woollen striped cloaks and their rida's were woollen garments. They were reciting the Talbiyah, performing pilgrimage to the Ancient House.”
