What is the expiation for someone who swore by Allah not to travel and then traveled, and does not possess the means to feed the poor, but his wife does? Should he fast for three consecutive or non-consecutive days?

The expiation for one who breaks an oath is one of three options, chosen at will: freeing a slave, or feeding ten poor persons, or clothing them. If one cannot afford any of these, then he moves to fasting three days. If the wife owns the means to feed, one is not obligated to take from her for the feeding. Fasting three days, consecutively or separately, becomes obligatory.
