حَدَّثَنَا خَلاَّدُ بْنُ يَحْيَى، حَدَّثَنَا مَالِكٌ، حَدَّثَنَا طَلْحَةُ بْنُ مُصَرِّفٍ، قَالَ سَأَلْتُ عَبْدَ اللَّهِ بْنَ أَبِي أَوْفَى ـ رضى الله عنهما ـ هَلْ كَانَ النَّبِيُّ صلى الله عليه وسلم أَوْصَى فَقَالَ لاَ. فَقُلْتُ كَيْفَ كُتِبَ عَلَى النَّاسِ الْوَصِيَّةُ أَوْ أُمِرُوا بِالْوَصِيَّةِ قَالَ أَوْصَى بِكِتَابِ اللَّهِ.
