Surah Az-Zukhruf, ayah 22

43:22

بَلۡ قَالُوٓاْ إِنَّا وَجَدۡنَآ ءَابَآءَنَا عَلَىٰٓ أُمَّةٖ وَإِنَّا عَلَىٰٓ ءَاثَٰرِهِم مُّهۡتَدُونَ ٢٢

Bal qālū innā wajadnā ābā'anā 'alā ummatin wa innā 'alā āthārihim muhtadūn

Rather, they say, "Indeed, we found our fathers upon a religion, and we are in their footsteps [rightly] guided."
