Sincerity in worship (ikhlas)

ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُم بِٱلَّيْلِ وَٱلنَّهَارِ سِرًّا وَعَلَانِيَةً فَلَهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ

Those who spend their wealth [in Allāh's way] by night and by day, secretly and publicly - they will have their reward with their Lord. And no fear will there be concerning them, nor will they grieve.

لَكُنَّا عِبَادَ ٱللَّهِ ٱلْمُخْلَصِينَ

We would have been the chosen servants of Allāh."

فَٱدْعُوا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ وَلَوْ كَرِهَ ٱلْكَـٰفِرُونَ

So invoke Allāh, [being] sincere to Him in religion, although the disbelievers dislike it.
