Surah Al-A'raf, ayah 33

قُلۡ إِنَّمَا حَرَّمَ رَبِّيَ ٱلۡفَوَٰحِشَ مَا ظَهَرَ مِنۡهَا وَمَا بَطَنَ وَٱلۡإِثۡمَ وَٱلۡبَغۡيَ بِغَيۡرِ ٱلۡحَقِّ وَأَن تُشۡرِكُواْ بِٱللَّهِ مَا لَمۡ يُنَزِّلۡ بِهِۦ سُلۡطَٰنٗا وَأَن تَقُولُواْ عَلَى ٱللَّهِ مَا لَا تَعۡلَمُونَ ٣٣

Qul innamā harrama rabbiyal-fawāhisha mā zahara minhā wamā batana wal-ithma wal-baghya bighayril-haqqi wa an tushrikū billāhi mā lam yunazzil bihī sultānan wa an taqūlū 'alallāhi mā lā ta'lamūn

Say, "My Lord has only forbidden immoralities - what is apparent of them and what is concealed - and sin,³⁶⁷ and oppression without right, and that you associate with Allāh that for which He has not sent down authority, and that you say about Allāh that which you do not know."
