أبو داود:٢٠٥٩حَدَّثَنَا عَبْدُ السَّلاَمِ بْنُ مُطَهِّرٍ أَنَّ سُلَيْمَانَ بْنَ الْمُغِيرَةِ حَدَّثَهُمْ عَنْ أَبِي مُوسَى عَنْ أَبِيهِ عَنِ ابْنٍ لِعَبْدِ اللَّهِ بْنِ مَسْعُودٍ عَنِ ابْنِ مَسْعُودٍ قَالَ

لاَ رِضَاعَ إِلاَّ مَا شَدَّ الْعَظْمَ وَأَنْبَتَ اللَّحْمَ فَقَالَ أَبُو مُوسَى لاَ تَسْأَلُونَا وَهَذَا الْحَبْرُ فِيكُمْ
