Narrated By Jabir bin ‘Abdullah : I fell ill, Allah’s Apostle and Abu Bakr came to visit me on foot. The Prophet came to me while I was unconscious. Allah’s Apostle performed ablution and poured the Remaining water of his ablution over me whereupon I became conscious and said, ‘O Allah’s Apostle! How should I spend my wealth? Or how should I deal with my wealth?” But the Prophet did not give me any reply till the Verse of the laws of inheritance was revealed.
