Arabic

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا وُهَيْبٌ، عَنِ ابْنِ طَاوُسٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى أَنْ يَبِيعَ الرَّجُلُ طَعَامًا حَتَّى يَسْتَوْفِيَهُ‏.‏ قُلْتُ لاِبْنِ عَبَّاسٍ كَيْفَ ذَاكَ قَالَ ذَاكَ دَرَاهِمُ بِدَرَاهِمَ وَالطَّعَامُ مُرْجَأٌ‏.‏ قَالَ أَبُو عَبْد اللَّهِ مُرْجَئُونَ مُؤَخَّرُونَ

Translation

Narrated Tawus:Ibn `Abbas said, "Allah's Messenger (ﷺ) forbade the selling of foodstuff before its measuring and transferring into one's possession." I asked Ibn `Abbas, "How is that?" Ibn `Abbas replied, "It will be just like selling money for money, as the foodstuff has not been handed over to the first purchaser who is the present seller
