Yûsuf 12:40
مَا تَعْبُدُونَ مِن دُونِهِ إِلَّا أَسْمَاءً سَمَّيْتُمُوهَا أَنتُمْ وَآبَاؤُكُم مَّا أَنزَلَ اللَّهُ بِهَا مِن سُلْطَانٍ ۚ إِنِ الْحُكْمُ إِلَّا لِلَّهِ ۚ أَمَرَ أَلَّا تَعْبُدُوا إِلَّا إِيَّاهُ ۚ ذَٰلِكَ الدِّينُ الْقَيِّمُ وَلَٰكِنَّ أَكْثَرَ النَّاسِ لَا يَعْلَمُونَ ٤٠
Ma taAAbudoona min doonihi illa asmaan sammaytumooha antum waabaokum ma anzala Allahu biha min sultanin ini alhukmu illa lillahi amara alla taAAbudoo illa iyyahu thalika alddeenu alqayyimu walakinna akthara alnnasi la yaAAlamoona
That which you serve, apart from Him, is nothing but names yourselves have named, you and your fathers; God has sent down no authority touching them. Judgment belongs only to God; He has commanded that you shall not serve any but Him. That is the right religion; but most men know not. (12:40)
