وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَطَاءِ بْنِ عَبْدِ اللَّهِ الْخُرَاسَانِيِّ، أَنَّهُ قَالَ حَدَّثَنِي شَيْخٌ، بِسُوقِ الْبُرَمِ بِالْكُوفَةِ عَنْ كَعْبِ بْنِ عُجْرَةَ، أَنَّهُ قَالَ جَاءَنِي رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَنَا أَنْفُخُ تَحْتَ قِدْرٍ لأَصْحَابِي وَقَدِ امْتَلأَ رَأْسِي وَلِحْيَتِي قَمْلاً فَأَخَذَ بِجَبْهَتِي ثُمَّ قَالَ ‏"‏ احْلِقْ هَذَا الشَّعَرَ وَصُمْ ثَلاَثَةَ أَيَّامٍ أَوْ أَطْعِمْ سِتَّةَ مَسَاكِينَ ‏"‏ ‏.‏ وَقَدْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَلِمَ أَنَّهُ لَيْسَ عِنْدِي مَا أَنْسُكُ بِهِ ‏.‏

Yahya related to me from Malik that Ata ibn Abdullah al-Khurasanisaid that an old man from Suq al-Buram in Kufa had related to him thatKab ibn Ujra said, "The Messenger of Allah, may Allah bless him andgrant him peace, came to me while I was blowing under a cooking potbelonging to my companions and my head and beard were full of lice. Hetook my forehead and said, 'Shave your hair and fast three days orfeed six poor people.' The Messenger of Allah, may Allah bless himand grant him peace, was aware that I did not have anything with me tosacrifice.'" Malik said, concerning paying compensation(fidya) for the relief of physical discomfort, "The custom concerningit is that no one pays compensation until he has done something whichmakes it obligatory to pay compensation just as making amends(kaffara) is only done when it has become obligatory for the one whoowes it. The person can pay the compensation wherever he wishes,regardless of whether he has to sacrifice an animal or fast or givesadaqa -- in Makka or in any other town." Malik said, "It isnot correct for a person in ihram to pluck out any of his hair or toshave it or cut it until he has left ihram, unless he is sufferingfrom an ailment of the head, in which case he owes the compensationAllah the Exalted has ordered. It is not correct for a person in ihramto cut his nails, or to kill his lice, or to remove them from his heador from his skin or his garment to the ground. If a person in ihramremoves lice from his skin or his garment, he must give away thequantity of food that he can scoop up with both hands. " Malik said,"Anyone who, while in ihram, plucks out hairs from his noseor armpit or rubs his body with a depilatory agent or shaves the hairfrom around a head wound out of necessity or shaves his neck for theplace of the cupping glasses, regardless of whether it is inforgetfulness or in ignorance, owes compensation in all theseinstances, and he must not shave the place of the cupping glasses.Someone, who, out of ignorance, shaves his head before he stones thejamra. must also pay compensation."
