وَإِذَا فَعَلُواْ فَٰحِشَةً قَالُواْ وَجَدۡنَا عَلَيۡهَآ ءَابَآءَنَا وَٱللَّهُ أَمَرَنَا بِهَا ۗ قُلۡ إِنَّ ٱللَّهَ لَا يَأۡمُرُ بِٱلۡفَحۡشَآءِ ۖ أَتَقُولُونَ عَلَى ٱللَّهِ مَا لَا تَعۡلَمُونَ
When they do aught that is shameful, they say: "We found our fathers doing so"; and "Allah commanded us thus": Say: "Nay, Allah never commands what is shameful: do ye say of Allah what ye know not?"<br/>
And when they commit any indecency, such as idolatry, or circumambulating the [Sacred] House naked, saying, 'We cannot perform the circumambulations wearing clothes in which we were disobedient to God' - and so they forbade this [wearing of clothes] - they say, 'We found our fathers practising it, and so we followed their example, and God has, also, enjoined it on us'. Say, to them: 'God does not enjoin indecency. Do you say concerning God that which you do not know?', that He has said? (the interrogative is meant as a repudiation).
