God will not punish you for that which is inadvertent in your oaths. But He will take you to task over the oaths which you solemnly swear. The penalty for a broken oath is the feeding of ten needy men with such food as you normally offer to your own people; or the clothing of ten needy men; or the freeing of a slave. He that cannot afford any of these must fast three days. In this way you shall expiate your broken oaths. Therefore be true to that which you have sworn. Thus God makes plain to you His revelations, so that you may give thanks.
