حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " نِعْمَ الْمَنِيحَةُ اللِّقْحَةُ الصَّفِيُّ مِنْحَةً، وَالشَّاةُ الصَّفِيُّ تَغْدُو بِإِنَاءٍ وَتَرُوحُ بِإِنَاءٍ ". حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ وَإِسْمَاعِيلُ عَنْ مَالِكٍ قَالَ نِعْمَ الصَّدَقَةُ.
