Al-Baqarah 2:225

La yu-akhithukumu Allahubillaghwi fee aymanikum walakin yu-akhithukumbima kasabat quloobukum wallahu ghafoorun haleem

Allāh does not impose blame upon you for what is unintentional in your oaths, but He imposes blame upon you for what your hearts have earned. And Allāh is Forgiving and Forbearing.

Allah does not hold you accountable for what is laghw (ineffectual) in your oaths, but He holds you accountable for what your hearts have produced. Allah is Forgiving, Forbearing.
