Allah shall not take you to task for what is frivolous in your oaths; but He shall take you to task for what you pledge in earnest. The atonement for it is to feed ten needy persons with the average food you give to your families, or their clothing, or the freeing of a slave. He who cannot afford [any of these] shall fast for three days. That is the atonement for your oaths when you vow. But keep your oaths. Thus does Allah clarify His signs for you so that you may give thanks.
