Allah will not take you to task for that which is unintentional in your oaths , but He will take you to task for the oaths which ye swear in earnest . The expiation thereof is the feeding of ten of the needy with the average of that wherewith ye feed your own folk , or the clothing of them , or the liberation of a slave , and for him who findeth not ( the wherewithal to do so ) then a three days ' fast .
