5:83And when they hear what was revealed to the Messenger, you see their eyes overflowing with tears, as they recognize the truth in it. They say, “Our Lord, we have believed, so count us among the witnesses.”

5:89God does not hold you accountable for your unintended oaths, but He holds you accountable for your binding oaths. The atonement for it is by feeding ten needy people from the average of what you feed your families, or by clothing them, or by freeing a slave. Anyone who lacks the means shall fast for three days. That is the atonement for breaking your oaths when you have sworn them. So keep your oaths. Thus God makes clear His Revelations to you, that you may be grateful.
