حَدَّثَنَا مُسَدَّدُ بْنُ مُسَرْهَدٍ حَدَّثَنَا يَحْيَی بْنُ سَعِيدٍ عَنْ عُبَيْدِ اللَّهِ حَدَّثَنِي نَافِعٌ عَنْ عَبْدِ اللَّهِ يَعْنِي ابْنَ عُمَرَ عَنْ رَسُولِ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَا حَقُّ امْرِئٍ مُسْلِمٍ لَهُ شَيْئٌ يُوصِي فِيهِ يَبِيتُ لَيْلَتَيْنِ إِلَّا وَوَصِيَّتُهُ مَکْتُوبَةٌ عِنْدَهُ
