أَخْبَرَنَا هَارُونُ بْنُ إِسْحَاقَ، قَالَ حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، عَنْ أَبِيهِ، عَنْ عُمَرَ، أَنَّهُ حَمَلَ عَلَى فَرَسٍ فِي سَبِيلِ اللَّهِ فَرَآهَا تُبَاعُ فَأَرَادَ شِرَاءَهَا فَقَالَ لَهُ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ لاَ تَعْرِضْ فِي صَدَقَتِكَ ‏"‏ ‏.‏
