God will not take you to task for a slip in your oaths; but He will take you to task for such bonds as you have made by oaths, whereof the expiation is to feed ten poor persons with the average of the food you serve to your families, or to clothe them, or to set free a slave; or if any finds not the means, let him fast for three days. That is the expiation of your oaths when you have sworn; but keep your oaths. So God makes clear to you His signs; haply you will be thankful.
