al-Qasim bin Malik al-Mzny

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.

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

Narrated As-Sa'ib bin Yazid:The Sa' (a kind of measure) during the lifetime of the Prophet (ﷺ) used to be equal to the one Mudd (another kind of measure) and one third of a Mudd which we use today, but the Sa' of today has become large.
