Is the wedding gift (al-shabaka) the right of the wife, and if so, can the two parties agree to compensate the husband with a sum of money, or must it be given in kind?

The matter has details:

1. If the husband gave her the jewelry as a gift or a donation, it is her property and he has no right to take it. 2. If he gave it to her as part of the dowry or if custom dictated it, it is also hers and he has no right to reclaim it. 3. If he gave it to her to wear and adorn herself with, and he has the right to take it whenever he wishes, or if he stipulated that it be with her as long as she is his wife and then return to him after separation, then he has the right to reclaim it and she must hand it over to him, unless he agrees to accept something in its place or its value.
