It is narrated from Sayyiduna Abu Raihanah (may Allah be pleased with him), he says: It has reached us that the Messenger of Allah (peace and blessings be upon him) forbade these matters: filing the teeth, tattooing, plucking hair, shighar (exchange marriage), a man lying with a man and a woman lying with a woman in one garment, adding hair to a woman's hair, and the sale of mulamasah (a type of uncertain sale).
