Sahih Bukhari Volume 6, Book 65, Hadith 4579

حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، حَدَّثَنَا هِشَامٌ، أَنَّ ابْنَ جُرَيْجٍ، أَخْبَرَهُمْ قَالَ أَخْبَرَنِي ابْنُ مُنْكَدِرٍ، عَنْ جَابِرٍ ـ رضى الله عنه ـ قَالَ عَادَنِي النَّبِيُّ صلى الله عليه وسلم وَأَبُو بَكْرٍ فِي بَنِي سَلِمَةَ مَاشِيَيْنِ فَوَجَدَنِي النَّبِيُّ صلى الله عليه وسلم لاَ أَعْقِلُ، فَدَعَا بِمَاءٍ فَتَوَضَّأَ مِنْهُ، ثُمَّ رَشَّ عَلَىَّ، فَأَفَقْتُ فَقُلْتُ مَا تَأْمُرُنِي أَنْ أَصْنَعَ فِي مَالِي يَا رَسُولَ اللَّهِ فَنَزَلَتْ ‏{‏يُوصِيكُمُ اللَّهُ فِي أَوْلاَدِكُمْ‏}‏

Narrated By Jabir : The Prophet and Abu Bakr came on foot to pay me a visit (during my illness) at Banu Salama's (dwellings). The Prophet found me unconscious, so he asked for water and performed the ablution from it and sprinkled some water over it. I came to my senses and said, "O Allah's Apostle! What do you order me to do as regards my wealth?" So there was revealed: "Allah commands you as regards your children's (inheritance)." (4.11)
