وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ لاَ يَغْسِلُ رَأْسَهُ وَهُوَ مُحْرِمٌ إِلاَّ مِنَ الاِحْتِلاَمِ . قَالَ مَالِكٌ سَمِعْتُ أَهْلَ الْعِلْمِ يَقُولُونَ لاَ بَأْسَ أَنْ يَغْسِلَ الرَّجُلُ الْمُحْرِمُ رَأْسَهُ بِالْغَسُولِ بَعْدَ أَنْ يَرْمِيَ جَمْرَةَ الْعَقَبَةِ وَقَبْلَ أَنْ يَحْلِقَ رَأْسَهُ وَذَلِكَ أَنَّهُ إِذَا رَمَى جَمْرَةَ الْعَقَبَةِ فَقَدْ حَلَّ لَهُ قَتْلُ الْقَمْلِ وَحَلْقُ الشَّعْرِ وَإِلْقَاءُ التَّفَثِ وَلُبْسُ الثِّيَابِ .
Yahya related to me from Malik from Nafi that Abdullah ibn Umarwould never wash his head while he was in ihram except if he had to doghusl because of a wet dream. Malik said, "I have heard thepeople of knowledge say that there is no harm in someone who is inihram rubbing his head with certain kinds of plants after he hasstoned the Jamrat al-Aqaba but before he has shaved his head, becauseonce he has finished stoning the Jamrat al-Aqaba it is halal for himto kill lice, to shave his head, to clean himself of body hair, and towear normal clothes."
