Book 11, Number 3932:

Jabir b. 'Abdullah (Allah be pleased with them) reported: I fell sick and there came to me on foot Allah's Messenger (may peace be upon him) and Abu Bakr for inquiring after my health. I fainted. He (the Holy Prophet) performed ablution and then sprinkled over me the water of his ablution. I felt some relief and said: Allah's Messenger, how should I decide about my property? He said nothing to me in response until this verse pertaining to the law of inheritance was revealed:" They ask you for a decision; say: Allah gives you a decision concerning the person who has neither parents nor children" (iv. 177).
