Is it permissible for a wife to pay the expiation for an oath (kaffarat al-yameen) on behalf of her procrastinating husband from her own money, and what is the solution to this issue?

Delaying the payment of expiation for an oath, despite being able to do so, is forbidden and incurs sin, because it is obligatory to pay it immediately. It is permissible for the wife to pay the expiation on behalf of her husband from her own money with his permission. One must be wary of swearing by divorce, as the lawful oath is by Allah, and some scholars have considered swearing by divorce to be the oath of the wicked. The husband should not make divorce the best ploy to solve his problems; rather, he should overlook, deliberate, and act with reason.
