Chapter on Growing Hair for Hajj and Umrah
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 44
وَ رُوِيَ عَنْ سَمَاعَةَ قَالَ: سَأَلْتُهُ عَنِ اَلْحِجَامَةِ وَ حَلْقِ اَلْقَفَا فِي أَشْهُرِ اَلْحَجِّ قَالَ «لاَ بَأْسَ وَ لاَ بَأْسَ بِالنُّورَةِ وَ اَلسِّوَاكِ ».
It is narrated from Sama‘ah, who said: I asked Imam عليه السلام about cupping and shaving the nape during the months of Hajj. Imam عليه السلام said: "There is no harm in it, nor in using Nuura (depilatory cream) or a toothstick (siwak)."
