It was narrated from Al-Ju'aid: "I heard As-Sa'ib bin Yazid say: 'During the time of Allah's messenger, the Sa' was equal to a Mudd and third of the Mudd you use today, and the Sa' of today has become large."' (Sahih) Abu 'Abdur-Rahman (An-Nasa'i) said: And Ziyad bin Ayyub narrated it to me.

It was narrated from Ibn 'Umar that the Prophet ( صلی اللہ علیہ وسلم ) said: "The measure (to be used) is the measure of the people of Al-Madinah, and the weight (to be used) is the weight of the people of Makkah."
