Chapter: Disciplines to Maintain in the State of al-’Ihram َيْدُ بْنُ زِيَادٍ عَنِ ابْنِ سَ٠َاعَةَ عَنْ غَيْرِ وَاحِدٍ عَنْ أَبَانٍ عَنْ زُرَارَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَ٠) هَلْ يَحُكُّ الْ٠ُ رَأْسَهُ وَيَغْتَسِلُ بِالْ٠َاءِ قَالَ يَحُكُّ رَأْسَهُ ٠َّدْ قَتْلَ دَابَّةٍ وَلا بَأْسَ بِأَنْ يَغْتَسِلَ بِالْ٠َاءِ وَيَصُبَّ عَلَى رَأْسِهِ ٠ُلَبِّداً فَإِنْ كَانَ ٠ُلَبِّداً فَلا يُفِيضُ عَلَى رَأْسِهِ الْ٠7.

Humayd ibn Ziyad has narrated from ibn Sama‘ah from more than one person from Aban from Zurarah who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man who is in the state of Ihram; if he can scratch his head and wash it with water.

He (the Imam) said, ‘He can scratch his head as long as he is certain of not killing a moving thing but it is not harmful to wash with water unless one’s head is treated with talbid (a medicine against lice), in which case one must not pour water over his head except because of wet-dream.’” وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (17/331))
