Ka'b b. 'Ujra (Allah be pleased with him) reported
The Messenger of Allah (ﷺ) came to me on the occasion of Hudaibiya and I was kindling fire under my cooking pot and lice were creeping on my face. Thereupon he (the Holy Prophet) said: Do the vermins harm your head? I said: Yes. He said: Get your head shaved and (in lieu of it) observe fasts for three days or feed six needy persons, or offer sacrifice (of an animal). Ayyub said: I do not know with what (type of expiation) did he commence (the statement).
This hadith is narrated on the authority of Ayyub.
Kalb b. Ujra (Allah be pleased with him) reported
It was I for whom this verse was revealed (to the Holy Prophet):" Whoever among you is sick or has an ail- ment of the head, he (may effect) a compensation by lasting or alms or a sacrifice" He said: I came to him (the Holy Prophet) and he said: Come Dear. So I went near. He (again) said: Come near. So I went near. Thereupon the Messenger of Allah (ﷺ) said: Do the vermins trouble you? Ibn Aun (one of the narrators) said: I think he (Ka'b b. Ujra) replied in the affirmative. He (the Holy Prophet) then commanded to do compensation by fasting or by giving sadaqa (feeding six needy persons) or by sacrifice (of a animal) that is available.
Ka'b b. 'Ujra (Allah be pleased with him) reported that the Messenger of Allah (may peace be, upon him) stood near him and lice were falling from his head. Thereupon he (the Holy Prophet) said
Do these vermins trouble you? I said: Yes. Thereupon he said: Then shave your head; and it was in connection with me that this verse was revealed:" Whoever among you is sick or has an ailment of the head, he (may effect) a compensation by fasting or alms or a sacrifice". He (the Holy Prophet, therefore) said to me: Observe fast for three days or give a quantity of alms enough to feed six needy persons or offer sacrifice (of an animal) that is available.
Ka`b b. 'Ujra (Allah be pleased with him) reported that the Messenger of Allah (ﷺ) happened to pass by him at Hudaibiya before entering Mecca in a state of Ihram and he (Ka'b) was kindling fire under the cooking pot and vermin were creeping on his (Ka`b's) face. Thereupon (the Holy Prophet) said
Do these vermin trouble you? He (Ka'b) said: Yes. The Messenger of Allah (way peace be upon him) said: Shave your head and give some quantity of food enough to feed six needy persons (faraq is equal to three sa's), or observe fast for three days or offer sacrifice of a sacrificial animal. Ibn Najih (one of the narrators) said:" Or sacrifice a goat."
Ka'b b. Ujra (Allah be pleased with him) reported that the Messenger of Allah (ﷺ) happened to pass by him during the period of Hudaibiya. Thereupon he (the Holy Prophet) said to him (Ka'b b. Ujra)
Do these vermins trouble your head? He said: Yes. Thereupon he (the Holy Prophet) said: Shave your head. Then sacrifice a goat or observe fasts for three days or give three sits of dates to feed six needy persons.
Abdullah b. Ma'qil said
I sat with Ka'b (Allah be pleased with him) and he was in the mosque. I asked him about this verse:" Compensation in (the form of) fasting, or Sadaqa or sacrifice." Ka'b (Allah be pleased with him) said: It was reveal- ed In my case. There was some trouble in my head. I was taken to the Messenger of Allah (ﷺ) and lice were creeping upon my face. Thereupon he said: I did not think that your trouble had become so unbearable as I see. Would you be able to afford (the sacrificing) of a goat? I (Ka'b) said: Then this verse was revealed:" Com- pensation (in the form of) fasting or alms or a sacrifice." He (the Holy Prophet) said: (It Implies) fasting for three days, or feeding six needy perscins, half sa' of food for every needy person. This verse was revealed particularly for me and (now) Its applica- tion is general for all of you.
Ka'b b. Ujra (Allah be pleased with him) reported that he went out with the Messenger of Allah (ﷺ) in the state of Ihram, and his (Ka'b's) head and beard were infested with lice. This was conveyed to the Messenger of Allah (ﷺ). He sent for him (Ka'b) and called a barber (who) shaved his head. He (the Holy Prophet) said. Is there any sacrificial animal with you? He (Kalb) said
I cannot afford it. He then commanded him to observe fasts for three days or feed six needy persons, one sa' for every two needy persons. And Allah the Exalted and Majestic revealed this (verse) particular with regard to him:" So whosoever among you is sick and has an ailment of the head.." ; then (its application) became general for the Muslims.
