حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا عَبْدُ الْوَارِثِ، عَنِ ابْنِ أَبِي نَجِيحٍ، حَدَّثَنِي عَبْدُ اللَّهِ، بْنُ كَثِيرٍ عَنْ أَبِي الْمِنْهَالِ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَدِمَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَالنَّاسُ يُسْلِفُونَ فَقَالَ لَهُمْ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏‏ ‏.‏ "‏ مَنْ أَسْلَفَ فَلاَ يُسْلِفْ إِلاَّ فِي كَيْلٍ مَعْلُومٍ وَوَزْنٍ مَعْلُومٍ ‏"
