The ruling on one who swears an oath and then breaks it

Question:
A brother of mine swore several oaths that I would accompany him to his home. It was late at night, so I swore an oath that I would not go with him. He said to me, “I have sworn several oaths, and you have sworn only one.” In the end, I went with him, though I was not pleased with this. Is the oath I swore considered a vain oath, or is expiation obligatory for it? If expiation is obligatory, please inform us what it is. May Allah reward you with good.

Answer:
Yes, expiation is obligatory for it, and praise be to Allah. If you accompany your brother in a manner that does not involve disobedience to Allah, there is no harm in it, and he owes the expiation for the oath. The Prophet (peace and blessings be upon him) commanded the fulfillment of the oath of the one who swore. So, if you helped your brother with a matter that does not anger Allah, you are rewarded, and you owe the expiation. The expiation is feeding ten poor people, or clothing them, or freeing a slave. If you cannot do any of these, you fast for three days. May Allah reward you with good.
