البيهقي:١٨١٣١أَخْبَرَنَا أَبُو أَحْمَدَ عَبْدُ اللهِ بْنُ مُحَمَّدِ بْنِ الْحَسَنِ الْمِهْرَجَانِيُّ أنبأ أَبُو بَكْرٍ مُحَمَّدُ بْنُ جَعْفَرٍ الْمُزَكِّي ثنا مُحَمَّدُ بْنُ إِبْرَاهِيمَ الْبُوشَنْجِيُّ ثنا ابْنُ بُكَيْرٍ ثنا مَالِكٌ عَنْ يَحْيَى بْنِ سَعِيدٍ

أَنَّ أَبَا بَكْرٍ الصِّدِّيقَ ؓ بَعَثَ جُيُوشًا إِلَى الشَّامِ فَذَكَرَ الْحَدِيثَ فِي وَصِيَّتِهِ إِلَى أَنْ قَالَ وَلَا تَعْقِرُنَّ شَاةً وَلَا بَعِيرًا إِلَّا لِمَأْكَلَةٍ
