Muhammad bin al-Munkadir (may Allah have mercy on him) said: I heard Jabir bin Abdullah (may Allah be pleased with him) say that the Messenger of Allah (peace and blessings be upon him) came to me while I was ill. He (peace and blessings be upon him) performed ablution (wudu) and sprinkled some of the water of his ablution on me. I said: O Messenger of Allah! Only a kalalah (one with neither parent nor child) will inherit from me, so how will the inheritance be divided? Then the verse of inheritance was revealed.
