[Machine] The Messenger of Allah ﷺ used to frequently perform ablution without any clear reason, so he poured water from his ablution onto me. Then he became conscious and I asked him if it meant that he was bequeathing me some inheritance. So, the verse of obligatory bequest was revealed.  

أَنَّ رَسُولَ اللهِ ﷺ عَادَهُ وَهُوَ لَا يَعْقِلُ فَتَوَضَّأَ فَصَبَّ عَلَيْهِ مِنْ وَضُوئِهِ فَعَقَلَ قُلْتُ يَرِثُنِي كَلَالَةٌ فَكَيْفَ الْمِيرَاثُ؟ فَأُنْزِلَ آيَةُ الْفَرْضِ  

I became sick so Messenger of Allah ﷺ and Abu Bakr came on foot to pay me a visit. When they came, I was unconscious. Messenger of Allah ﷺ performed ablution and he poured over me the water (of his ablution) and I came to my senses and said, "O Messenger of Allah ﷺ! What shall I do regarding my property? How shall I distribute it?" The Prophet ﷺ did not reply till the Divine Verses of inheritance were revealed . (Using translation from Bukhārī 6723)   

سَمِعْتُ جَابِرًا يَقُولُ مَرِضْتُ فَأَتَانِي رَسُولُ اللهِ ﷺ وَأَبُو بَكْرٍ يَعُودَانِي وَهُمَا يَمْشِيَانِ فَوَجَدَانِي قَدْ أُغْمِيَ عَلَيَّ فَتَوَضَّأَ رَسُولُ اللهِ ﷺ فَصَبَّ وَضُوءَهُ عَلَيَّ فَأَفَقْتُ فَقُلْتُ يَا رَسُولَ اللهِ كَيْفَ أَقْضِي فِي مَالِي؟ كَيْفَ أَصْنَعُ فِي مَالِي؟ فَلَمْ يُجِبْنِي بِشَيْءٍ حَتَّى أُنْزِلَتْ آيَةُ الْمِيرَاثِ {يَسْتَفْتُونَكَ قُلِ اللهُ يُفْتِيكُمْ فِي الْكَلَالَةِ} [النساء 176] قَالَ أَبُو عَبْدِ الرَّحْمَنِ خَالَفَهُ ابْنُ جُرَيْجٍ  

Allah's Apostle ﷺ and Abi Bakr (Allah be pleased with him) visited me on foot in Banu Salama, and found me unconscious. He (the Holy Prophet) called for water and performed ablution and sprinkled out of it (the water) over me. I felt relieved. I said: Messenger of Allah, what should I do with my property? And this verse was revealed:" Allah enjoins you concerning your children: for the male is equal of the portion of two females." (Using translation from Muslim 1616b)   

عَادَنِي النَّبِيُّ ﷺ وَأَبُو بَكْرٍ فِي بَنِي سَلَمَةَ فَوَجَدَانِي لَا أَعْقِلُ فَدَعَا بِمَاءٍ فَتَوَضَّأَ ثُمَّ رَشَّ عَلَيَّ مِنْهُ فَأَفَقْتُ فَقُلْتُ لَهُ كَيْفَ أَصْنَعُ فِي مَالِي يَا رَسُولَ اللهِ؟ فَأَنْزَلَ اللهُ {يُوصِيكُمُ اللهُ فِي أَوْلَادِكُمْ لِلذَّكَرِ مِثْلُ حَظِّ الْأُنْثَيَيْنِ} [النساء 11]
