حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكِ بْنِ أَنَسٍ، فِيمَا قُرِئَ عَلَيْهِ عَنْ إِسْحَاقَ بْنِ عَبْدِ، اللَّهِ بْنِ أَبِي طَلْحَةَ عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " اللَّهُمَّ بَارِكْ لَهُمْ فِي مِكْيَالِهِمْ وَبَارِكْ لَهُمْ فِي صَاعِهِمْ وَبَارِكْ لَهُمْ فِي مُدِّهِمْ " .
