Surah Adh-Dhariyat — Ayah 53

وَلَا تَجْعَلُوا۟ مَعَ ٱللَّهِ إِلَـٰهًا ءَاخَرَ ۖ إِنِّى 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 مَآ أَتَى ٱلَّذِينَ مِن قَبْلِهِم مِّن رَّسُولٍ إِلَّا قَالُوا۟ سَاحِرٌ أَوْ مَجْنُونٌ

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

فَتَوَلَّ عَنْهُمْ فَمَآ أَنتَ بِمَلُومٍ

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

وَذَكِّرْ فَإِنَّ ٱلذِّكْرَىٰ تَنفَعُ ٱلْمُؤْمِنِينَ

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