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."  

لَقَدْ ضَلَلْتُ إِذًا وَمَا أَنَا مِنَ الْمُهْتَدِينَ وَلَكِنِّي سَأَقْضِي فِيهَا بِقَضَاءِ النَّبِيِّ ﷺ لاِبْنَتِهِ النِّصْفُ وَلاِبْنَةِ الاِبْنِ سَهْمٌ تَكْمِلَةُ الثُّلُثَيْنِ وَمَا بَقِيَ فَلِلأُخْتِ مِنَ الأَبِ وَالأُمِّ  

We went out with the Messenger of Allah ﷺ and came to a woman of the Ansar in al-Aswaf. The woman brought her two daughters, and said: Messenger of Allah, these are the daughters of Thabit ibn Qays who was killed as a martyr when he was with you at the battle of Uhud, their paternal uncle has taken all their property and inheritance, and he has not left anything for them. What do you think, Messenger of Allah? They cannot be married unless they have some property. The Messenger of Allah ﷺ said: Allah will decide regarding the matter. Then the verse of Surat an-Nisa was revealed: "Allah (thus) directs you as regards your children's (inheritance)." Messenger of Allah ﷺ said: Call to me the woman and her husband's brother. He then said to their paternal uncle: Give them two-thirds and their mother an eighth, and what remains is yours. Abu Dawud said: The narrator Bishr made a mistake. They were the daughters of Sa'd b. al-Rabi' for Thabit b. Qais was killed in the battle of Yamamah.  

خَرَجْنَا مَعَ رَسُولِ اللَّهِ ﷺ حَتَّى جِئْنَا امْرَأَةً مِنَ الأَنْصَارِ فِي الأَسْوَاقِ فَجَاءَتِ الْمَرْأَةُ بِابْنَتَيْنِ لَهَا فَقَالَتْ يَا رَسُولَ اللَّهِ هَاتَانِ بِنْتَا ثَابِتِ بْنِ قَيْسٍ قُتِلَ مَعَكَ يَوْمَ أُحُدٍ وَقَدِ اسْتَفَاءَ عَمُّهُمَا مَالَهُمَا وَمِيرَاثَهُمَا كُلَّهُ فَلَمْ يَدَعْ لَهُمَا مَالاً إِلاَّ أَخَذَهُ فَمَا تَرَى يَا رَسُولَ اللَّهِ فَوَاللَّهِ لاَ تُنْكَحَانِ أَبَدًا إِلاَّ وَلَهُمَا مَالٌ فَقَالَ رَسُولُ اللَّهِ ﷺ يَقْضِي اللَّهُ فِي ذَلِكَ قَالَ وَنَزَلَتْ سُورَةُ النِّسَاءِ { يُوصِيكُمُ اللَّهُ فِي أَوْلاَدِكُمْ } الآيَةَ فَقَالَ رَسُولُ اللَّهِ ﷺ ادْعُوا لِيَ الْمَرْأَةَ وَصَاحِبَهَا فَقَالَ لِعَمِّهِمَا أَعْطِهِمَا الثُّلُثَيْنِ وَأَعْطِ أُمَّهُمَا الثُّمُنَ وَمَا بَقِيَ فَلَكَ  

The wife of Sa'd b. al-Rabi said: Messenger of Allah, Sa'd died and left two daughters. He then narrated the rest of the tradition in a similar way. Abu Dawud said: This is the most correct tradition.  

يَا رَسُولَ اللَّهِ إِنَّ سَعْدًا هَلَكَ وَتَرَكَ ابْنَتَيْنِ وَسَاقَ نَحْوَهُ  

Mu'adh b. Jabal gave shares of inheritance to a sister and a daughter. He gave each of them half. He was at Yemen while the Prophet ﷺ was alive.  

أَنَّ مُعَاذَ بْنَ جَبَلٍ وَرَّثَ أُخْتًا وَابْنَةً فَجَعَلَ لِكُلِّ وَاحِدَةٍ مِنْهُمَا النِّصْفَ وَهُوَ بِالْيَمَنِ وَنَبِيُّ اللَّهِ ﷺ يَوْمَئِذٍ حَىٌّ
