﴿ وَإِذَا فَعَلُوا۟ فَٰحِشَةًۭ قَالُوا۟ وَجَدْنَا عَلَيْهَآ ءَابَآءَنَا وَٱللَّهُ أَمَرَنَا بِهَا ۗ قُلْ إِنَّ ٱللَّهَ لَا يَأْمُرُ بِٱلْفَحْشَآءِ ۖ أَتَقُولُونَ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ ﴾

“and [so,] whenever they commit a shameful deed, they are wont to say, "We found our forefathers doing it," and, "God has enjoined it upon us." Say: "Behold, never does God enjoin deeds of abomination. Would you attribute unto God something of which you have no knowledge?"”
