The Drawstring
Scholars have said that seeing a drawstring in trousers may indicate matters related to marriage, such as the wife becoming forbidden or divorced. It might also signify giving birth to two daughters for a pregnant woman, or not accepting a child if placed under the head. The breaking of a drawstring could point to a husband's poor treatment of his wife or the annulment of a marriage contract, while a drawstring made of blood suggests killing a man because of a woman or assisting in killing an adulterous woman.
