Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) "forbade shighar (exchange marriage)", and "shighar is that a man arranges his daughter's marriage with another man on the condition that the other gives him his own daughter in marriage, with no dowry (mahr) between them"; but Yahya did not mention the other man.
