Hadith 1529
Chapter 8: It is invalid to sell goods before taking possession of them - كتاب البيوع
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا رَوْحٌ، حَدَّثَنَا ابْنُ جُرَيْجٍ، حَدَّثَنِي أَبُو الزُّبَيْرِ، أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَقُولُ " إِذَا ابْتَعْتَ طَعَامًا فَلاَ تَبِعْهُ حَتَّى تَسْتَوْفِيَهُ " .
Jabir b. Abdullah (Allah be pleased with them) reported Allah's Messenger (ﷺ) as saying:
When you purchase foodgrains, do not sell them until you have taken possession of them.
