وَمَا أَرْسَلْنَا مِن قَبْلِكَ مِن رَّسُولٍ إِلَّا نُوحِي إِلَيْهِ أَنَّهُ لَا إِلَهَ إِلَّا أَنَا فَاعْبُدُونِ
[21:25]
And We did not send before you any messenger but We revealed to him that there is no god but Me, therefore serve Me.
Not a messenger did We send before thee without this inspiration sent by Us to him: that there is no god but I; therefore worship and serve Me.
And We sent no messenger before thee but We inspired him, (saying): There is no Allah save Me (Allah), so worship Me.
