Chapter 190 | The Prohibited Matters that Become Lawful for One after Shaving and Before Performing Tawaf of Ziyarat
2ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنْ يُونُسَ بْنِ يَعْقُوبَ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) فَقُلْتُ الْمُتَمَتِّعُ يُغَطِّي رَأْسَهُ إِذَا حَلَقَ فَقَالَ يَا بُنَيَّ حَلْقُ رَأْسِهِ أَعْظَمُ مِنْ تَغْطِيَتِهِ إِيَّاهُ.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from Yunus ibn Ya’qub who has said the following: “I once asked abu ‘Abd Allah , about a man who is for al-Tamattu‘ (advantageous); if he can cover his head after shaving. He (the Imam) said, ‘Son, shaving is greater than his covering it.’”
