Hadith #1

مُحَمَّدُ بْنُ يَحْيَى عَنِ الْعَمْرَكِيِّ بْنِ عَلِيٍّ عَنْ عَلِيِّ بْنِ جَعْفَرٍ عَنْ أَخِيهِ أَبِي الْحَسَنِ ( عليه السلام ) قَالَ سَأَلْتُهُ عَنْ مَوْلُودٍ يُحْلَقُ رَأْسُهُ بَعْدَ يَوْمِ السَّابِعِ فَقَالَ إِذَا مَضَى سَبْعَةُ أَيَّامٍ فَلَيْسَ عَلَيْهِ حَلْقٌ .

1. Muhammad ibn Yahya has narrated from al-‘Amrakiy ibn Ali from Ali ibn Ja‘far from his brother abu al-Hassan, ‘Alayhi al-Salam, who has said the following: “I once asked abu al-Hassan, ‘Alayhi al-Salam, about the newborn: if shaving his head after seven days from his birth is required. He (the Imam) said, ‘When seven days pass shaving is not required.’”
