The Prohibition Of Selling Food Before Taking Possession Of It
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنِ ابْنِ أَبِي لَيْلَى، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ نَهَى رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ عَنْ بَيْعِ الطَّعَامِ حَتَّى يَجْرِيَ فِيهِ الصَّاعَانِ صَاعُ الْبَائِعِ وَصَاعُ الْمُشْتَرِي .
It was narrated that Jabir said: 'The Messenger of Allah (ﷺ) forbade selling food bought by measure until two Sa' have been measured - the Sa' of the seller and the Sa' of the buyer."[1]
