HAIR Arabic sha’r, sha’ar شعر
The sale of human hair is unlawful in the same manner as the use of it for any purpose is unlawful. Being a part of the human body, it is necessary to preserve it from disgrace, to which an exposure of it to sale necessarily subjects it. It is related in the traditions that God has cursed women who use false hair. (Hidayah, vol. ii. p 439 [HEAD].
