Al-Baqara (2:170)
وَإِذَا قِیلَ لَهُمُ ٱتَّبِعُوا۟ مَاۤ أَنزَلَ ٱللَّهُ قَالُوا۟ بَلۡ نَتَّبِعُ مَاۤ أَلۡفَیۡنَا عَلَیۡهِ ءَابَاۤءَنَاۤۚ أَوَلَوۡ كَانَ ءَابَاۤؤُهُمۡ لَا یَعۡقِلُونَ شَیۡـࣰٔا وَلَا یَهۡتَدُونَ
And when it is said unto them: Follow that which Allah hath revealed, they say: We follow that wherein we found our fathers. What! Even though their fathers were wholly unintelligent and had no guidance?
