Narrated Jabir:

I fell ill, and the Prophet (ﷺ) and Abu Bakr came to me on foot to visit me. As I was unconscious, I could not speak to him. He performed ablution and sprinkled water on me ; so I became conscious. I said: Messenger of Allah, how should I do in my property, as I have sisters? Thereafter the verse about inheritance was revealed: "They ask you for legal decision. Say: Allah directs (thus) about those who leave no descendants or ascendants as heirs."

حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا سُفْيَانُ، قَالَ سَمِعْتُ ابْنَ الْمُنْكَدِرِ، أَنَّهُ سَمِعَ جَابِرًا، يَقُولُ مَرِضْتُ فَأَتَانِي النَّبِيُّ صلى الله عليه وسلم يَعُودُنِي هُوَ وَأَبُو بَكْرٍ مَاشِيَيْنِ وَقَدْ أُغْمِيَ عَلَىَّ فَلَمْ أُكَلِّمْهُ فَتَوَضَّأَ وَصَبَّهُ عَلَىَّ فَأَفَقْتُ فَقُلْتُ يَا رَسُولَ اللَّهِ كَيْفَ أَصْنَعُ فِي مَالِي وَلِي أَخَوَاتٌ قَالَ فَنَزَلَتْ آيَةُ الْمَوَارِيثِ ‏{‏ يَسْتَفْتُونَكَ قُلِ اللَّهُ يُفْتِيكُمْ فِي الْكَلاَلَةِ ‏}‏ ‏.‏
