I heard `Umar bin `Abdul `Aziz telling about As-Sa’ib bin Yazid that he had performed Hajj (while carried) with the belongings of the Prophet.
I saw As-Sa’ib bin Yazid when he was ninety-four years old, quite strong and of straight figure. He said, “I know that I enjoyed my hearing and seeing powers only because of the invocation of Allah’s Apostle . My aunt took me to him and said, ‘O Allah’s Messenger (ﷺ)! My nephew is sick; will you invoke Allah for him?’ So he invoked (Allah) for me.”
As-Sa’ib bin Yazid said, “The Sa’ at the time of the Prophet (ﷺ) was equal to one Mudd plus one-third of a Mudd of your time, and then it was increased in the time of Caliph `Umar bin `Abdul `Aziz.”
