It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) forbade shighar marriage (exchange marriage). Shighar is that a man says: Marry your daughter to me and I will marry my daughter to you, or: Marry your sister to me and I will marry my sister to you. And the Noble Prophet (peace and blessings be upon him) forbade deceptive trade and selling by throwing pebbles.
