Hadith 54
The Book of Financial Transactions
It was narrated that Ibn 'Umar said:
"The Messenger of Allah said: "Volume is to be measured according to the system of the people of Al-Madinah, and weight is to be measured according to the system of the peole of Makkah."' (Sahih) This is the wording of Ishaq (one of the narrators).
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، عَنِ الْمُلاَئِيِّ، عَنْ سُفْيَانَ، ح وَأَنْبَأَنَا مُحَمَّدُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا أَبُو نُعَيْمٍ، عَنْ سُفْيَانَ، عَنْ حَنْظَلَةَ، عَنْ طَاوُسٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
الْمِكْيَالُ عَلَى مِكْيَالِ أَهْلِ الْمَدِينَةِ وَالْوَزْنُ عَلَى وَزْنِ أَهْلِ مَكَّةَ
