Quran 7:28 Al-A'raf, ayah 28 of 206

وَإِذَا فَعَلُوا۟ فَـٰحِشَةً قَالُوا۟ وَجَدْنَا عَلَيْهَآ ءَابَآءَنَا وَٱللَّهُ أَمَرَنَا بِهَا ۗ قُلْ إِنَّ ٱللَّهَ لَا يَأْمُرُ بِٱلْفَحْشَآءِ ۖ أَتَقُولُونَ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ ۝٢٨

7:28 And when they do some lewdness they say: We found our fathers doing it and Allah hath enjoined it on us. Say: Allah, verily, enjoineth not lewdness. Tell ye concerning Allah that which ye know not?
