Sayyiduna Jabir (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) visited me in my illness, and so did Sayyiduna Abu Bakr (may Allah be pleased with him), among Banu Salimah, and he found me unconscious. The Prophet (peace and blessings be upon him) called for water, performed ablution (wudu), and then sprinkled some of it on me. When I recovered, I said: O Messenger of Allah (peace and blessings be upon him)! What shall I do with my wealth? Then this verse was revealed: "Allah instructs you concerning your children: for the male, the like of the share of two females." [Surah al-Nisa: 11].
