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

And do not set up another god alongside God. Truly I am a clear warner to you from Him (before fa-firrū, ‘so flee’, one may read an implicit ˹preceding˺ qul lahum, ‘Say to them’).
القرآن:٥١:٥١ –

وَلَا تَجْعَلُوا مَعَ اللَّهِ إِلَٰهًا آخَرَ ۖ إِنِّي لَكُمْ مِنْهُ نَذِيرٌ مُبِينٌ  

{ولا تجعلوا مع الله إلها آخر إني لكم منه نذير مبين} يقدر قبل ففروا قل لهم.
