Surah Yusuf (Joseph), Verse 40

مَا تَعْبُدُوْنَ مِنْ دُوْنِهٖۤ اِلَّاۤ اَسْمَآءً سَمَّیْتُمُوْهَاۤ اَنْتُمْ وَاٰبَآؤُكُمْ مَّاۤ اَنْزَلَ اللّٰهُ بِهَا مِنْ سُلْطٰنٍ اِنِ الْحُكْمُ اِلَّا لِلّٰهِ اَمَرَ اَلَّا تَعْبُدُوْۤا اِلَّاۤ اِیَّاهُ ذٰلِكَ الدِّیْنُ الْقَیِّمُ وَلٰكِنَّ اَكْثَرَ النَّاسِ لَا یَعْلَمُوْنَ ۟

Maa ta'budoona min doonihee illaaa asmaaa'an sam maitumoohaaa antum wa aabaaa'ukum maaa anzalal laahu bihaa min sultan; inilhukmu illaa lillaah; amara allaa ta'budooo illaaa iyyaah; zaalikad deenul qaiyimu wa laakinna aksaran naasi laa ya'lamoon

“"If not Him, ye worship nothing but names which ye have named,- ye and your fathers,- for which Allah hath sent down no authority: the command is for none but Allah: He hath commanded that ye worship none but Him: that is the right religion, but most men understand not...”
