Jabir b. Abdullah (Allah be pleased with him) reported: Whilo I was ill Allah's Messenger (may peace be upon him) came to me and found me unconscious. He (the Holy Prophet) performed ablution, and sprinkled over me the water of his ablution. I regained my consciousness and said: Allah's Messenger, my case of inheritance is that of Kalala. Then the verse pertaining to the inheritance ( of Kalala) was revealed. I (one of the narrators) said: I said to Muhammad b. Munkadir: (Do you mean this verse)" They ask you; say: Allah gives you decision in regard to Kalala" (iv. 177)? He said: Yes, it was thus revealed.
