مَا تَعْبُدُونَ مِن دُونِهِۦٓ إِلَّآ أَسْمَآءًۭ سَمَّيْتُمُوهَآ أَنتُمْ وَءَابَآؤُكُم مَّآ أَنزَلَ ٱللَّهُ بِهَا مِن سُلْطَٰنٍ ۚ إِنِ ٱلْحُكْمُ إِلَّا لِلَّهِ ۚ أَمَرَ أَلَّا تَعْبُدُوٓا۟ إِلَّآ إِيَّاهُ ۚ ذَٰلِكَ ٱلدِّينُ ٱلْقَيِّمُ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ
Those whom ye worship beside Him are but names which ye have named, ye and your fathers. Allah hath revealed no sanction for them. The decision rests with Allah only, Who hath commanded you that ye worship none save Him. This is the right religion, but most men know not.
Surah Yusuf(12:40)
