[Machine] The Messenger of Allah ﷺ forbade a man from selling food unless he has fully received it. Tawus said, "I said to Ibn Abbas, 'How is that?' He replied, 'That means exchanging dirhams for dirhams, and the food is deferred.'"
أَنَّ رَسُولَ اللهِ ﷺ نَهَى أَنْ يَبِيعَ الرَّجُلُ طَعَامًا حَتَّى يَسْتَوْفِيَهُ قَالَ طَاوُسٌ فَقُلْتُ لِابْنِ عَبَّاسٍ فَكَيْفَ ذَلِكَ؟ قَالَ ذَلِكَ دَرَاهِمُ بِدَرَاهِمَ وَالطَّعَامُ مُرْجَأٌ
