What is the ruling on returning money sent by a suitor who apostatized from Islam during the engagement period? Will Allah guide him if this money is given as charity with the intention of guiding him? Is the repeated failure to complete an engagement due to magic or due to Allah's wrath?

An answer was previously given regarding the ruling on a suitor's gift to his fiancée if the marriage does not take place. In this particular issue, since the suitor apostatized from Islam, his gift should not be returned to him. Instead, it should be used for the general welfare of the Muslims and not be given as charity on his behalf, because the property of an apostate is placed in the Muslim treasury. As for the failure of the engagement, Allah alone knows the reason and wisdom behind it. You should adhere to piety and be content with His decree, remembering His saying: "But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah Knows, while you know not."
