Unlawful oaths/wrong swearing and its compensation

Allâh will not punish you for what is unintentional in your oaths, but He will punish you for your deliberate oaths; for its expiation feed ten Masâkîn (poor persons), on a scale of the average of that with which you feed your own families, or clothe them or manumit a slave. But whosoever cannot afford (that), then he should fast for three days. That is the expiation for the oaths when you have sworn[]. And protect your oaths (i.e. do not swear much)[]. Thus Allâh make clear to you His Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.) that you may be grateful.

Comment
I consider this applied to all the matters that Allah will not punish us for our unintentional sins.I expect mercy from Him as He is the Most Merciful and Oft-forgiving
