Sayyiduna al-Dahhak bin Qays (may Allah be pleased with him) narrates that in Madinah there was a woman who used to circumcise women, called Umm Atiyyah. the Messenger of Allah (peace and blessings be upon him) said to her: "Cut lightly and do not cut away completely, for that brings more freshness to the face and is more pleasing to the husband."
