What is the ruling on one who swore four oaths and broke them, then fed ten poor people bananas, water, a pastry, and juice each, as an expiation for those oaths? Is this feeding sufficient, or is another feeding obligatory? And what is the amount of expiation that must be given?

If a Muslim breaks an oath for a beneficial purpose, he must offer expiation by feeding ten poor people with food of the average quality and type that he feeds his own family, or clothing them, or emancipating a slave. If he cannot find any of these, then he must fast for three days.

"Average" here means the mean between extravagance and stinginess. It is permissible to restrict the feeding to rice and wheat. Scholars have differed on the exact amount of food for feeding. The most cautious approach is to give one mudd of food to each poor person (approximately 750 grams of rice), or half a sa' (approximately 1.5 kilograms). The most cautious approach is to give the food to the poor people as outright ownership. Although it is permissible, according to the preponderant opinion, to feed them lunch and dinner, giving them ownership of the food is better to avoid dispute.

Expiation is measured by volume, not by weight.
