God does not hold you responsible for the mere utterance of oaths; He holds you responsible for your innermost intentions. God is Forgiver, Clement.
لا يُؤاخِذُكُمُ اللَّهُ بِاللَّغوِ فى أَيمٰنِكُم وَلٰكِن يُؤاخِذُكُم بِما كَسَبَت قُلوبُكُم وَاللَّهُ غَفورٌ حَليمٌ
laa yu’aakhi zukumul laahu billaghwi feee aymaa nikum wa laakiny yu’aakhi zukum bimaa kasabat quloo bukum; wallaahu Ghafoorun Haleem
