Hadith 513770
Chapter 31: Business Transactions - كتاب البيوع
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ، قَالَ فِي رَجُلٍ أَسْلَفَ رَجُلاً طَعَامًا عَلَى أَنْ يُعْطِيَهُ إِيَّاهُ فِي بَلَدٍ آخَرَ فَكَرِهَ ذَلِكَ عُمَرُ بْنُ الْخَطَّابِ وَقَالَ فَأَيْنَ الْحَمْلُ يَعْنِي حُمْلاَنَهُ .
Yahya related to me from Malik that he had heard that Umar ibn al-Khattab said that he disapproved of one man lending another food on the provision that he gave it back to him in another city. He said, "Where is the transport?"
