I wrote to Imam (as) regarding a man who proposed marriage to his uncle's daughter. The uncle instructed one of his brothers to marry his daughter to the man. However, during the marriage contract, the man mistakenly mentioned a different name instead of the daughter's actual name, which was Fatimah. The man did not have any daughter by the name he mentioned during the contract. The Imam (as) responded: "There is no harm in it."
