أبو داود:٢١٩٢حَدَّثَنَا ابْنُ السَّرْحِ حَدَّثَنَا ابْنُ وَهْبٍ عَنْ يَحْيَى بْنِ عَبْدِ اللَّهِ بْنِ سَالِمٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْحَارِثِ الْمَخْزُومِيِّ عَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ

أَنَّ النَّبِيَّ ﷺ قَالَ فِي هَذَا الْخَبَرِ زَادَ وَلاَ نَذْرَ إِلاَّ فِيمَا ابْتُغِيَ بِهِ وَجْهُ اللَّهِ تَعَالَى ذِكْرُهُ
