quran:40:14 –

So invoke Allah, ˹being˺ sincere to Him in religion, although the disbelievers dislike it.  

So supplicate God, worship Him, devoting ˹your˺ religion purely to Him, ˹free˺ from any idolatry, however much the disbelievers be averse, to its being free of such ˹idolatry˺.
القرآن:٤٠:١٤ –

فَادْعُوا اللَّهَ مُخْلِصِينَ لَهُ الدِّينَ وَلَوْ كَرِهَ الْكَافِرُونَ  

{فادعوا الله} اعبدوه {مخلصين له الدين} من الشرك {ولو كره الكافرون} إخلاصكم منه.
