What is required of one who swore to visit the Sacred House of God during the first holiday he obtained, but did not do so because he went to take exams outside the country?

The questioner owes an expiation for breaking an oath, because he swore to do something at a specific time and then failed to do it when that time passed. The expiation for an oath is to feed ten needy persons from the average of what one feeds his own family, or to clothe them, or to free a slave. And whoever cannot find [the means], then he must fast three days. That is the expiation for oaths.
