Surah Al-Baqarah (The Cow), Verse 225

لَا یُؤَاخِذُكُمُ اللّٰهُ بِاللَّغْوِ فِیْۤ اَیْمَانِكُمْ وَلٰكِنْ یُّؤَاخِذُكُمْ بِمَا كَسَبَتْ قُلُوْبُكُمْ وَاللّٰهُ غَفُوْرٌ حَلِیْمٌ ۟

Laa yu'aakhi zukumul laahu billaghwi feee aymaa nikum wa laakiny yu'aakhi zukum bimaa kasabat quloo bukum; wallaahu Ghafoorun Haleem

“Allah will not call you to account for thoughtlessness in your oaths, but for the intention in your hearts; and He is Oft-forgiving, Most Forbearing.”
