“oaths”
in Edition Clear Qur'an by Talal Itani / Al-Maaida (The Table)
5:53Those who believe will say, “Are these the ones who swore by God with their strongest oaths that they are with you?” Their works have failed, so they became losers.
5:89God does not hold you accountable for your unintended oaths, but He holds you accountable for your binding oaths. The atonement for it is by feeding ten needy people from the average of what you feed your families, or by clothing them, or by freeing a slave. Anyone who lacks the means shall fast for three days. That is the atonement for breaking your oaths when you have sworn them. So keep your oaths. Thus God makes clear His Revelations to you, that you may be grateful.
5:108That makes it more likely that they will give true testimony, fearing that their oaths might be contradicted by subsequent oaths. So fear God, and listen. God does not guide the disobedient people.

Those who spend their wealth by night and day, privately and publicly, will receive their reward from their Lord. They have nothing to fear, nor shall they grieve.
