Is a marriage contract valid if the guardian says to the suitor: "I give you my virgin, mature daughter in marriage," while both the suitor and the guardian know that the fiancée made a mistake in the past and repented?

If a girl repents, she is not obligated to inform her suitor about her past; rather, she should conceal it. Since she did inform him and he agreed, it is permissible for the guardian to say: "I give you my virgin daughter in marriage." This is a lie for the sake of concealment and causes no harm. Indeed, permission to lie has been granted in three specific cases, and it can be extended to situations necessitated by dire need or an overriding benefit, such as lying to protect a Muslim from an oppressor. In such instances, one should use equivocation (ma'arid) if possible.
