What is the ruling on reclaiming the value of the Shabka (engagement gift) after the engagement is annulled by the bride's side, given that her family had presented its value to the bride in money? Is there any prohibition in insisting on that? And is it permissible to propose to the bride before resolving the issue?

The engagement is merely a promise of marriage, and it is permissible to break it, although it is disliked without a valid need. If the engagement is broken, there is no harm in another person proposing to her, for it is impermissible to propose over the proposal of one's brother unless the first suitor has abandoned the proposal, or given permission, or if the situation is unknown. As for the jewelry (shabka), if it was presented as part of the dowry or if custom dictates it as such, then it must be returned in its original form if the engagement is broken, as long as it remains intact, and not its value.
