A pilgrim returned from Mecca, got married thereafter, and was blessed with children; he later found out that he did not perform Tawaf-un-Nisaa, what is the ruling on his marriage and children?
His marriage is deemed valid since what becomes haram after shaving the hair and before Tawaf-un-Nisaa is intimacy and pleasure with the spouse and not conducting a marriage contract, and the children are considered legitimately his, regardless of the situation.
