A grandmother came to AbuBakr asking him for her share of inheritance. He said: There is nothing prescribed for you in Allah's Book, nor do I know anything for you in the Sunnah of the Prophet of Allah ﷺ Go home till I question the people. He then questioned the people, and al-Mughirah ibn Shu'bah said: I had been present with the Messenger of Allah ﷺ when he gave grandmother a sixth. AbuBakr said: Is there anyone with you? Muhammad ibn Maslamah stood and said the same as al-Mughirah ibn Shu'bah had said. So AbuBakr made it apply to her. Another grandmother came to Umar ibn al-Khattab asking him for her share of inheritance. He said: Nothing has been prescribed for you in Allah's Book. The decision made before you was made for a grandmother other than you. I am not going to add in the shares of inheritance; but it is that sixth. If there are two of you, it is shared between you, but whichever of you is the only one left gets it all. (Using translation from Abū Dāʾūd 2894)   

جَاءَتِ الْجَدَّةُ إِلَى أَبِي بَكْرٍ الصِّدِّيقِ ؓ تَسْأَلُهُ مِيرَاثَهَا فَقَالَ لَهَا أَبُو بَكْرٍ ؓ مَا لَكِ فِي كِتَابِ اللهِ شَيْءٌ وَمَا عَلِمْتُ لَكِ فِي سُنَّةِ رَسُولِ اللهِ ﷺ شَيْئًا فَارْجِعِي حَتَّى أَسْأَلَ النَّاسَ فَقَالَ الْمُغِيرَةُ بْنُ شُعْبَةَ حَضَرْتُ رَسُولَ اللهِ ﷺ أَعْطَاهَا السُّدُسَ فَقَالَ أَبُو بَكْرٍ هَلْ مَعَكَ غَيْرُكَ؟ فَقَامَ مُحَمَّدُ بْنُ مَسْلَمَةَ الْأَنْصَارِيُّ فَقَالَ مِثْلَ مَا قَالَ الْمُغِيرَةُ فَأَنْفَذَهُ لَهَا أَبُو بَكْرٍ ؓ ثُمَّ جَاءَتِ الْجَدَّةُ الْأُخْرَى إِلَى عُمَرَ بْنِ الْخَطَّابِ ؓ تَسْأَلُهُ مِيرَاثَهَا فَقَالَ مَا لَكِ فِي كِتَابِ اللهِ شَيْءٌ وَمَا كَانَ الْقَضَاءُ الَّذِي قَضَى بِهِ إِلَّا لِغَيْرِكِ وَمَا أَنَا بِزَائِدٍ فِي الْفَرَائِضِ شَيْئًا وَلَكِنْ هُوَ ذَاكَ السُّدُسُ فَإِنِ اجْتَمَعْتُمَا فِيهِ فَهُوَ بَيْنَكُمَا وَأَيَّتُكُمَا خَلَتْ بِهِ فَهُوَ لَهَا  

It was narrated from Ibn ‘Abbas that the Messenger of Allah ﷺ gave a grandmother one sixth of the inheritance. (Using translation from Ibn Mājah 2725)   

أَنَّ رَسُولَ اللهِ ﷺ وَرَّثَ جَدَّةً سُدُسًا  

[Machine] That the Messenger of Allah ﷺ would give one-sixth of the inheritance to the grandmother if she is not a mother.  

أَنَّ رَسُولَ اللهِ ﷺ أَطْعَمَ السُّدُسَ الْجَدَّةَ إِذَا لَمْ تَكُنْ أُمٌّ  

[Machine] The Prophet Muhammad ﷺ gave the grandmother one-sixth and it was narrated from Shu'bah from Yunus ibn 'Ubayd, 12341 Abu al-Hasan ibn 'Abdan informed us, I am Ahmad ibn 'Ubayd narrated by Muhammad ibn Bishr, the brother of Khattab, narrated by Ibn Humayd, narrated by Ibrahim ibn al-Mukhtar, narrated by Shu'bah, who mentioned it similarly.  

أَنَّ رَسُولَ اللهِ ﷺ أَعْطَى الْجَدَّةَ السُّدُسَ وَرُوِيَ عَنْ شُعْبَةَ عَنْ يُونُسَ بْنِ عُبَيْدٍ 12341 أَخْبَرَنَا أَبُو الْحَسَنِ بْنُ عَبْدَانَ أنا أَحْمَدُ بْنُ عُبَيْدٍ ثنا مُحَمَّدُ بْنُ بِشْرٍ أَخُو خَطَّابٍ ثنا ابْنُ حُمَيْدٍ ثنا إِبْرَاهِيمُ بْنُ الْمُخْتَارِ ثنا شُعْبَةُ فَذَكَرَهُ بِمِثْلِهِ وَكَذَلِكَ  

[Machine] He said, "The two grandmothers came to Abu Bakr Al-Siddiq, and he wanted to give the sixth to the one from the mother's side. A man from the Ansar said to him, 'Why don't you leave it to the one who, if they were to die while he is alive, he would inherit from her?' So Abu Bakr Al-Siddiq placed the sixth between them."  

أَنَّهُ قَالَ أَتَتِ الْجَدَّتَانِ إِلَى أَبِي بَكْرٍ الصِّدِّيقِ ؓ فَأَرَادَ أَنَ يَجْعَلَ السُّدُسَ لِلَّتِي مِنْ قِبَلِ الْأُمِّ فَقَالَ لَهُ رَجُلٌ مِنَ الْأَنْصَارِ أَمَا إِنَّكَ تَتْرُكُ الَّتِي لَوْ مَاتَتَا وَهُوَ حَيٌّ كَانَ إِيَّاهَا يَرِثُ فَجَعَلَ أَبُو بَكْرٍ الصِّدِّيقُ السُّدُسَ بَيْنَهُمَا  

[Machine] That my two grandmothers, Umm Al-Umm and Umm Al-Abe, came to Abu Bakr Al-Siddiq. So Abu Bakr gave the inheritance to Umm Al-Umm over Umm Al-Abe. Abdurrahman bin Sahl, the brother of Bani Haritha, said to him, "O Khalifa of the Messenger of Allah, you have given to one who, if she were to die, would not be inherited." So Abu Bakr placed Abu Bakr between them, meaning one-sixth, and this is narrated from the Prophet ﷺ in a mursal chain.  

أَنَّ جَدَّتَيْنِ أَتَتَا أَبَا بَكْرٍ الصِّدِّيقَ ؓ أُمُّ الْأُمِّ وَأُمُّ الْأَبِ فَأَعْطَى الْمِيرَاثَ أُمَّ الْأُمِّ دُونَ أُمِّ الْأَبِ فَقَالَ لَهُ عَبْدُ الرَّحْمَنِ بْنُ سَهْلٍ أَخُو بَنِي حَارِثَةَ يَا خَلِيفَةَ رَسُولِ اللهِ قَدْ أَعْطَيْتَ الَّتِي لَوْ أَنَّهَا مَاتَتْ لَمْ يَرِثْهَا فَجَعَلَهُ أَبُو بَكْرٍ بَيْنَهُمَا يَعْنِي السُّدُسَ وَقَدْ رُوِيَ هَذَا عَنِ النَّبِيِّ ﷺ فِي إِسْنَادٍ مُرْسَلٍ  

[Machine] Indeed, it is from the decree of the Messenger of Allah ﷺ that he has decreed for the two grandmothers from the inheritance a sixth (of total inheritance), whether from Is-haq or 'Ubadah, the one being sent.  

إِنَّ مِنْ قَضَاءِ رَسُولِ اللهِ ﷺ أَنَّهُ قَضَى لِلْجَدَّتَيْنِ مِنَ الْمِيرَاثِ بَيْنَهُمَا السُّدُسُ سَوَاءٌ إِسْحَاقُ عَنْ عُبَادَةَ مُرْسَلٌ
