What is the ruling regarding a dhimmi gifting wine to another dhimmi, which subsequently turns into vinegar while in the recipient's possession, followed by the giver divorcing the recipient before consummation?
General Chapter
Al-Mughni
Book of Dowry (Mahr)
Primary text
It is probable that the giver shall not have recourse against the recipient for anything. This is because the substance in her possession increased in value through the process of acidification (takhallul), and this increase belongs to her. If the giver seeks the return of half its value prior to acidification, then it has no value. Recourse is only established if the substance increased in value by half its value from the time of the contract until the time of possession; in that case, it has no value.

It is also probable that the vinegar belongs to the giver, and he owes her half of the dower equivalent (mahr mithliha), especially if they both or one of them refer the dispute to us before possession or after submitting (to our ruling).
