And there is no blame on you respecting that which you speak indirectly in the asking of (such) women in marriage or keep (the proposal) concealed within your minds; Allah knows that you will mention them, but do not give them a promise in secret unless you speak in a lawful manner, and do not confirm the marriage tie until the writing is fulfilled, and know that Allah knows what is in your minds, therefore beware of Him, and know that Allah is Forgiving, Forbearing.
