God will not catch you up for a casual word in your oaths, but He will catch you up for having what ye make deliberate oaths about; and the expiation thereof is to feed ten poor men with the middling food ye feed your families withal, or to clothe them, or to free a neck; but he who has not the means, then let him fast three days. That is the expiation of your oaths, when ye have sworn to keep your oaths; thus does God explain to you His signs, - haply ye may be grateful.
