Section : How Much of Her Hair a Woman is to Cut Off.
Ibn ‘Umar said, “When a woman (pilgrim) wants to cut off her hair, she may hold her hair at the front and cut it off about the length of the tip of a finger.” In ‘Ata’s opinion, while cutting her hair, a woman should cut it off her sides, of the long hair as well as the short ones. This is reported by Sa’id bin Mansur. Others hold that there is no limit as to how much a woman may cut off her hair. The Shafi’i school holds that cutting as much as three hairs is enough for a female pilgrim.
