Do not use your oaths to deceive each other lest any foot should slip after being firmly placed and lest you should taste the penalty for having hindered others from the path of God, and suffer terrible torment.
Do not turn your oaths into a means of deceit among yourselves, lest a foot slip after being firmly planted, and you taste the bitterness of having turned others from the way of God — and a great punishment awaits you.
