٤- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ عَلِيِّ بْنِ أَسْبَاطٍ عَنْ خَلَفِ بْنِ حَمَّادٍ عَنْ عَمْرِو بْنِ ثَابِتٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ كَانَتِ امْرَأَةٌ يُقَالُ لَهَا أُمُّ طَيْبَةَ تَخْفِضُ الْجَوَارِيَ فَدَعَاهَا النَّبِيُّ (صَلَّى اللهُ عَلَيْهِ وَآلِه) فَقَالَ لَهَا يَا أُمَّ طَيْبَةَ إِذَا خَفَضْتِ الْجَوَارِيَ فَأَشِمِّي وَلا تُجْحِفِي فَإِنَّهُ أَصْفَى لِلَوْنِ الْوَجْهِ وَأَحْظَى عِنْدَ الْبَعْلِ. 
4. A number of our people have narrated from Sahl ibn Ziyad from Ali ibn Asbat from Khalaf ibn Hammad from ibn Thabit who has said the following: “Abu ‘Abd Allah, Alayhi al-Salam, has said, ‘There was a woman called ‘Umm Taybah. She would circumcise girls. The Holy Prophet, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, called her and said to her, ‘O ‘Umm Taybah, when you circumcise girls do not allow it to become excessive. It clears the color of the face and is more enjoyable for the husband.’”
