What is the ruling on the list of marital movables and the Mahr (dowry), given a dispute between the suitor, who refuses to write it, seeing it as materialistic, and the fiancée's father, who considers it a guarantee of his daughter's rights?

The list of movables is permissible in Islamic law because it is a customary practice that does not contradict theibilities of the Sharia. There is no harm if the girl's guardian requests its written documentation to safeguard his daughter's rights, especially since this resolves any potential future disputes. If the suitor insists on not documenting it, the right can be proven through testimony, as the purpose of the list is to establish the wife's right. These financial matters are the wife's right, so she has the option to waive them or their documentation.
