The Prophet ﷺ said: (The standard) weight is the weight of the people of Mecca, and the (standard) measure is the measure of the people of Medina. Abu Dawud said: Al-Firyabi and Abu Ahmad have also transmitted from Sufyan in a similar way, and he (Ibn Dukain) agreed with them on the text. The version of Abu Ahmad has: "from Ibn 'Abbas" instead of Ibn 'Umar. It has also been transmitted by al-Walid b. Muslim from Hanzalah. This version has: "the weight of Medina and the measure of Mecca." Abu Dawud said: There is a variation in the text of the version of this tradition narrated by Malik b. Dinar from 'Ata' from the Prophet ﷺ.  

قَالَ رَسُولُ اللَّهِ ﷺ الْوَزْنُ وَزْنُ أَهْلِ مَكَّةَ وَالْمِكْيَالُ مِكْيَالُ أَهْلِ الْمَدِينَةِ
