God will not take you to task for those of your oaths which you may utter without thought, but He will take you to task for oaths which you have sworn in earnest. The breaking of an oath must be atoned for by the feeding of ten needy people with more or less the same food as you normally give to your own families, or by clothing them, or by the freeing of one slave. He who cannot afford any of these shall fast three days instead. This shall be the atonement for your oaths when you have sworn [and broken them]. But be mindful of your oaths. Thus God makes clear to you His revelations, so that you may give thanks.
