Narrated Al-Ju'aid bin `Abdur-Rahman: As-Sa'ib bin Yazid said, "The Sa' at the time of the Prophet 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."

Narrated Al-Ju'aid bin `Abdur-Rahman: 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.
