16ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ عَبْدِ الله بْنِ الْمُغِيرَةِ عَنِ ابْنِ مُسْكَانَ عَنْ مُحَمَّدٍ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ لاَ تَنْقُضُ الْمَرْأَةُ شَعْرَهَا إِذَا اغْتَسَلَتْ مِنَ الْجَنَابَةِ.
16. Ali ibn Ibrahim has narrated from his father from ‘Abd Allah ibn al-Mughirah from ibn Muskan from Muhammad al-Halabiy who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘It is not necessary for a woman to open up her hairs when taking Ghusl (bath) because of sexual relation.’”
