2ـ عَلِيٌّ عَنْ أَبِيهِ عَنْ حَمَّادٍ عَنْ حَرِيزٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ السُّنَّةُ فِي الإِحْرَامِ تَقْلِيمُ الأَظْفَارِ وَأَخْذُ الشَّارِبِ وَحَلْقُ الْعَانَةِ.
2. Ali has narrated from his father from Hammad from Hariz who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘Of the Sunnah in Ihram is to trim finger nails, mustache and pubic hairs.’”
