Surat Al-'A`rāf - سورة الأعراف

وَإِذَا فَعَلُوا فَاحِشَةً قَالُوا وَجَدْنَا عَلَيْهَا آبَاءَنَا وَاللَّهُ أَمَرَنَا بِهَا ۗ قُلْ إِنَّ اللَّهَ لَا يَأْمُرُ بِالْفَحْشَاءِ ۖ أَتَقُولُونَ عَلَى اللَّهِ مَا لَا تَعْلَمُونَ

: And when they commit a Fahisha (evil deed, going round the Ka'bah in naked state, every kind of unlawful sexual intercourse, etc.), they say: "We found our fathers doing it, and Allah has commanded us of it." Say: "Nay, Allah never commands of Fahisha. Do you say of Allah what you know not?
