﴿ ۞ وَقَالَ ٱللَّهُ لَا تَتَّخِذُوٓا۟ إِلَٰهَيْنِ ٱثْنَيْنِ ۖ إِنَّمَا هُوَ إِلَٰهٌۭ وَٰحِدٌۭ ۖ فَإِيَّٰىَ فَٱرْهَبُونِ ﴾

“And God has said: "Do not take to worshipping two [or more] deities. He is the One and Only God: hence, of Me, of Me alone stand in awe!"”

(Allah hath said: Choose not) worship not (two gods) i.e. Himself as well as the idols. (There is only One God) without a son or partner. (So of Me, Me only, be in awe) fear Me in relation to worshipping idols.
