It was narrated that Abdullah bin Maqil said: "I sat with Kab bin Ujrah in the Masjid and asked him about this Verse: He must pay a compensation of either fasting (three days) or giving charity (feeding six poor persons) or offering sacrifice (one sheep) Ka’b said: It was revealed concerning me. I had trouble with my head, so I was carried to the Messenger of Allah, with lice crawling on my face. He said: I did not think that you were suffering as much as I see. Do you have a sheep?’ I said: ‘No.’ Then this Verse was revealed: "He must pay a Fidyah (ransom) of either fasting (three days) or ‘Sadaqah (charity- feeding six poor persons) or offering sacrifice (one sheep). He said: Fasting is three days, chariy is to be given to six poor persons, giving each one half a Sa of food, and the sacrifice is a sheep.’”
