The Sufficient (Vol 6) · Hadith 2107 (#Ḥadīth #3)

عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ قَالَ قُلْتُ لِأَبِي الْحَسَنِ ( عليه السلام ) إِنَّ أَصْحَابَنَا يَرْوُونَ أَنَّ حَلْقَ الرَّأْسِ فِي غَيْرِ حَجٍّ وَ لَا عُمْرَةٍ مُثْلَةٌ فَقَالَ كَانَ أَبُو الْحَسَنِ ( عليه السلام ) إِذَا قَضَى مَنَاسِكَهُ عَدَلَ إِلَى قَرْيَةٍ يُقَالُ لَهَا سَايَةُ فَحَلَقَ .

3. A number of our people have narrated from Sahl ibn Ziyad Ahmad ibn Muhammad from ibn abu Nasr who has said the following: “I once said to abu al-Hassan , ‘Our people narrate that shaving one’s head, except for al-Hajj or al-‘Umrah, is like causing deformity.’ He (the Imam) said, ‘Abu al-Hassan , after al-Hajj and al-‘Umrah would go to the town called Sayah and shave his head.’”
