Swearing is mentioned in the Quran in these verses:

[2:224] Do not subject God’s name to your casual swearing, that you may appear righteous, pious, or to attain credibility among the people. God is Hearer, Knower.

[16:91] You shall fulfill your covenant with God when you make such a covenant. You shall not violate the oaths after swearing (by God) to carry them out, for you have made God a guarantor for you. God knows everything you do.
