Narrated Jabir:
حَدَّثَنَا أَبُو الْوَلِيدِ ، قَالَ حَدَّثَنَا شُعْبَةُ ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ ، قَالَ سَمِعْتُ جَابِرًا ، يَقُولُ جَاءَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَعُودُنِي، وَأَنَا مَرِيضٌ لاَ أَعْقِلُ، فَتَوَضَّأَ وَصَبَّ عَلَىَّ مِنْ وَضُوئِهِ ، فَعَقَلْتُ فَقُلْتُ يَا رَسُولَ اللَّهِ لِمَنِ الْمِيرَاثُ إِنَّمَا يَرِثُنِي كَلاَلَةٌ. فَنَزَلَتْ آيَةُ الْفَرَائِضِ .
Allah's Messenger (ﷺ) came to visit me while I was sick and unconscious. He performed ablution and sprinkled the remaining water on me and I became conscious and said, "O Allah's Messenger (ﷺ)! To whom will my inheritance go as I have neither ascendants nor descendants?" Then the Divine verses regarding Fara'id (inheritance) were revealed.
