Is it permissible to pay the monetary value of the expiation for an unfulfilled oath (kaffarat al-dhihar) to several people instead of feeding the poor?

The default for expiation (kaffarah) for Zihar (a pre-Islamic form of divorce) is feeding, and it is not permissible to deviate from it as long as it is possible.

Some scholars hold the view that it is permissible to give money if it is more beneficial for the poor, but this is a weak opinion.

The expiation for Zihar follows the following order: freeing a slave, and if one cannot find one, then fasting for two consecutive months, and if one is unable to do that, then feeding sixty poor people, based on the Almighty’s saying: "And those who pronounce Zihar on their wives and then wish to go back on what they said - then [there must be] the freeing of a slave before they touch one another. That is an admonition for you, and Allah is acquainted with what you do. And he who does not find [a slave] - then a fast for two consecutive months before they touch one another. And he who is unable to do so - then the feeding of sixty poor persons."
