Quran 10:29 from Surah Yunus on Divine Marvels.
فَكَفَىٰ بِٱللَّهِ شَهِيدَۢا بَيۡنَنَا وَبَيۡنَكُمۡ إِن كُنَّا عَنۡ عِبَادَتِكُمۡ لَغَٰفِلِينَ
English translation: So sufficient (is) Allah (as) a witness between us and between you that we were of your worship certainly unaware
Transliteration: fakafa bil-lahi shahidan baynana wabaynakum in kunna an ibadatikum laghafilina
