Sunan Abi Dawud 2890
Narrated Huzail b. Shurahbil al-Awadi:
A man came to Abu Musa al-Ash'ari and Salman b. Rabi'ah, and asked about a case where there were a daughter, a son's daughter and full sister. They replied: The daughter gets half and the full gets half. The son's daughter gets nothing. Go to Ibn Mas'ud and you will find that he agrees with me. So the man came to him and informed him about their opinion. He said: I would then be in error and not be one of those who are rightly guided. But I decide concerning the matter as the Messenger of Allah (ﷺ) did: The daughter gets half, and the son's daughter gets a share which complete thirds (i.e. gets a sixth), and what remain to the full sister."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَامِرِ بْنِ زُرَارَةَ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنِ الأَعْمَشِ، عَنْ أَبِي قَيْسٍ الأَوْدِيِّ، عَنْ هُزَيْلِ بْنِ شُرَحْبِيلَ الأَوْدِيِّ، قَالَ جَاءَ رَجُلٌ إِلَى أَبِي مُوسَى الأَشْعَرِيِّ وَسَلْمَانَ بْنِ رَبِيعَةَ فَسَأَلَهُمَا عَنِ ابْنَةٍ وَابْنَةِ ابْنٍ وَأُخْتٍ، لأَبٍ وَأُمٍّ فَقَالاَ لاِبْنَتِهِ النِّصْفُ وَلِلأُخْتِ مِنَ الأَبِ وَالأُمِّ النِّصْفُ وَلَمْ يُوَرِّثَا ابْنَةَ الاِبْنِ شَيْئًا وَأْتِ ابْنَ مَسْعُودٍ فَإِنَّهُ سَيُتَابِعُنَا فَأَتَاهُ الرَّجُلُ فَسَأَلَهُ وَأَخْبَرَهُ بِقَوْلِهِمَا فَقَالَ لَقَدْ ضَلَلْتُ إِذًا وَمَا أَنَا مِنَ الْمُهْتَدِينَ وَلَكِنِّي سَأَقْضِي فِيهَا بِقَضَاءِ النَّبِيِّ صلى الله عليه وسلم لاِبْنَتِهِ النِّصْفُ وَلاِبْنَةِ الاِبْنِ سَهْمٌ تَكْمِلَةُ الثُّلُثَيْنِ وَمَا بَقِيَ فَلِلأُخْتِ مِنَ الأَبِ وَالأُمِّ ‏.‏
