Is it permissible to switch to fasting in the case of multiple expiations, given the meager salary and the insufficiency of what remains for feeding after essential living expenses?

Expiation through fasting is only valid for those who are unable to feed ten poor people, or clothe them, or free a slave, according to the Almighty's saying: "But whoever finds none - then a fast of three days." The inability to offer expiation must be at the time of the oath-breaking. Thus, fasting is not sufficient if, after the cost of feeding, there remains enough for your sustenance and the sustenance of your dependents. Some scholars are of the view that fasting is sufficient for someone who is eligible to receive zakat (definition).
