654. Commandment – To safe guard your oaths and the expiation if you break the oath

[5:90] Allah will not call you to account for such of your oaths as are vain, but He will call you to account for the oaths which you take in earnest. The expiation for this is the feeding of ten poor persons with such average food as you feed your families with, or the clothing of them or the freeing of a neck. But whoso finds not the means shall fast for three days. That is the expiation of your oaths when you have sworn them. And do keep your oaths. Thus does Allah explain to you His Signs that you may be grateful.

[2:226] Allah will not call you to account for such of your oaths as are vain, but He will call you to account for what your hearts have earned. And Allah is Most Forgiving, Forbearing.

[38:45] And We said to him, ‘Take in thy hand a handful of dry twigs and strike therewith, and break not thy oath.’ Indeed, We found him steadfast. An excellent servant was he. Surely, he was always turning to God.
