Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he (peace be upon him) said: "There is no Shighar (a type of marriage) in Islam." And that is when a woman is married in exchange for the dowry of another woman, he says: Marry her to me and I will marry her to you, and there will be no dowry; this is called Shighar.
