Chapter 188 | Shaving and Trimming One’s Nails or Hair
7ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ عَلَى الصَّرُورَةِ أَنْ يَحْلِقَ رَأْسَهُ وَلا يُقَصِّرَ وَإِنَّمَا التَّقْصِيرُ لِمَنْ حَجَّ حَجَّةَ الإِسْلامِ.
7. A number of our people have narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad from Ali ibn abu Hamzah from abu Basir who has said the following: “Abu ‘Abd Allah , has said, ‘Al-Sarura (one who performs al-Hajj for the first time) must shave his head and must not do Taqsir (cutting some hair or finger nails and so on); it is for those who have already performed Hajjahta al-Islam.’”
