Adh-Dhariyat 51:53

فَفِرُّوا إِلَى اللَّهِ ۖ إِنِّي لَكُم مِّنْهُ نَذِيرٌ مُّبِينٌ

So flee to Allah. Indeed, I am to you from Him a clear warner.

وَلَا تَجْعَلُوا مَعَ اللَّهِ إِلَـٰهًا آخَرَ ۖ إِنِّي لَكُم مِّنْهُ نَذِيرٌ مُّبِينٌ

And do not make [as equal] with Allah another deity. Indeed, I am to you from Him a clear warner.

كَذَٰلِكَ مَا أَتَى الَّذِينَ مِن قَبْلِهِم مِّن رَّسُولٍ إِلَّا قَالُوا سَاحِرٌ أَوْ مَجْنُونٌ

Similarly, there came not to those before them any messenger except that they said, "A magician or a madman."

فَتَوَلَّ عَنْهُمْ فَمَا أَنتَ بِمَلُومٍ

So leave them, [O Muhammad], for you are not to be blamed.

وَذَكِّرْ فَإِنَّ الذِّكْرَىٰ تَنفَعُ الْمُؤْمِنِينَ

And remind, for indeed, the reminder benefits the believers.

وَمَا خَلَقْتُ الْجِنَّ وَالْإِنسَ إِلَّا لِيَعْبُدُونِ

And I did not create the jinn and mankind except to worship Me.
