حَدَّثَنَا هُشَيْمٌ عَنِ ابْنِ أَبِي لَيْلَى عَنْ أَبِي قَيْسٍ عَنْ هُزَيْلِ بْنِ شُرَحْبِيلَ أَنَّ الْأَشْعَرِيَّ أُتِيَ فِي ابْنَةٍ وَابْنَةِ ابْنٍ وَأُخْتٍ لِأَبٍ وَأُمٍّ قَالَ فَجَعَلَ لِلِابْنَةِ النِّصْفَ وَلِلْأُخْتِ مَا بَقِيَ وَلَمْ يَجْعَلْ لِابْنَةِ الِابْنِ شَيْئًا قَالَ فَأَتَوْا ابْنَ مَسْعُودٍ فَأَخْبَرُوهُ قَالَ فَقَالَ لَقَدْ ضَلَلْتُ إِذَنْ وَمَا أَنَا مِنْ الْمُهْتَدِينَ إِنْ أَخَذْتُ بِقَوْلِهِ وَتَرَكْتُ قَوْلَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ ثُمَّ قَالَ ابْنُ مَسْعُودٍ لِلِابْنَةِ النِّصْفُ وَلِابْنَةِ الِابْنِ السُّدُسُ وَمَا بَقِيَ لِلْأُخْتِ
مسند امام احمد بن حنبل · Hadith 4073
It was narrated from Huzail bin Shurahbeel that al-Ash'ari was asked about a daughter, a son's daughter, a sister through the father and mother (full sister) [i.e., a case of inheritance]. He allocated half to the daughter and the rest to the sister, and he did not allocate anything to the son's daughter. They went to Ibn Mas'ood and told him (about that) and he said: I would go astray, and I would not be one of the rightly guided (cf. 6:45) it i accepted his verdict and ignored the verdict of the Messenger of Allah (PBUH). Then Ibn Mas'ood said: The daughter gets one half, the son's daughter gets one sixth and what is left goes to the sister.
