Can the value of furniture and appliances bought by the husband for the wife's apartment, which is approximately 35,000 EGP, be considered part of the agreed-upon deferred dowry (mu'akhar al-sadaq) of 15,000 EGP in case of separation, and what are the wife's rights in this situation?

The deferred dowry is fully due to the divorced woman if the divorce occurs after consummation, and half of it if it occurs before. As for the household furniture, its ruling varies depending on its owner. If the furniture belongs to the husband and the wife agrees to take it in exchange for waiving the deferred dowry, there is no harm in that. It is advisable not to hasten divorce as long as marital life can be preserved.
