Narrated Jabir bin `Abdullah:The Prophet (ﷺ) came to me while I was ill. He performed ablution and threw the remaining water on me (or said, "Pour it on him) " When I came to my senses I said, "O Allah's Messenger (ﷺ)! I have no son or father to be my heir, so how will be my inheritance?" Then the Verse of inheritance was revealed.
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا غُنْدَرٌ، حَدَّثَنَا شُعْبَةُ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، قَالَ سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ قَالَ دَخَلَ عَلَىَّ النَّبِيُّ صلى الله عليه وسلم وَأَنَا مَرِيضٌ فَتَوَضَّأَ فَصَبَّ عَلَىَّ أَوْ قَالَ صُبُّوا عَلَيْهِ فَعَقَلْتُ فَقُلْتُ لاَ يَرِثُنِي إِلاَّ كَلاَلَةٌ، فَكَيْفَ الْمِيرَاثُ فَنَزَلَتْ آيَةُ الْفَرَائِضِ.
