وَإِذَا فَعَلُوا۟ فَـٰحِشَةً قَالُوا۟ وَجَدْنَا عَلَيْهَآ ءَابَآءَنَا وَٱللَّهُ أَمَرَنَا بِهَا ۗ قُلْ إِنَّ ٱللَّهَ لَا يَأْمُرُ بِٱلْفَحْشَآءِ ۖ أَتَقُولُونَ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ
wa-idhā faʿalū fāḥishatan qālū wajadnā ʿalayhā ābāanā wal-lahu amaranā bihā qul inna l-laha lā yamuru bil-faḥshāi ataqūlūna ʿalā l-lahi mā lā taʿlamūna
Yet when [these people] do something disgraceful, they say, ‘We found our forefathers doing this,’ and, ‘God has commanded us to do this.’ Say [Prophet], ‘God does not command disgraceful deeds. How can you say about God things that you do not know [to be true]?’
And when they commit a Fâhishah (evil deed, going round the Ka‘bah in naked state, and every kind of unlawful sexual intercourse), they say: "We found our fathers doing it, and Allâh has commanded it on us." Say: "Nay, Allâh never commands Fâhishah. Do you say of Allâh what you know not?"
