حَدَّثَنَا عَفَّانُ حَدَّثَنَا وُهَيْبٌ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ طَاوُسٍ عَنْ أَبِيهِ عَنِ ابْنِ عَبَّاسٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى أَنْ يَبِيعَ الرَّجُلُ طَعَامًا حَتَّى يَسْتَوْفِيَهُ قَالَ فَقُلْتُ لَهُ كَيْفَ ذَلِكَ قَالَ ذَلِكَ دَرَاهِمُ بِدَرَاهِمَ وَالطَّعَامُ مُرْجَأٌ
مسند امام احمد بن حنبل · Hadith 2275
It was narrated from ibn 'Abbas (RA) that the Messenger of Allah (PBUH) forbade selling foodstuff until it has been received in full. I [the narrator] said to him: Why was that? He said: It would be just like selling dirhams for dirhams , as the food is something postponed.
