Surah Az-Zumar, verse 13

قُلْ إِنِّىٓ أُمِرْتُ أَنْ أَعْبُدَ ٱللَّهَ مُخْلِصًۭا لَّهُ ٱلدِّينَ ﴿١١﴾

Say, [O Muḥammad], "Indeed, I have been commanded to worship Allāh, [being] sincere to Him in religion.

وَأُمِرْتُ لِأَنْ أَكُونَ أَوَّلَ ٱلْمُسْلِمِينَ ﴿١٢﴾

And I have been commanded to be the first [among you] of the Muslims."

قُلِ ٱللَّهَ أَعْبُدُ مُخْلِصًۭا لَّهُۥ دِينِى ﴿١٤﴾

Say, "Allāh [alone] do I worship, sincere to Him in my religion,

فَٱعْبُدُوا۟ مَا شِئْتُم مِّن دُونِهِۦ ۗ قُلْ إِنَّ ٱلْخَـٰسِرِينَ ٱلَّذِينَ خَسِرُوٓا۟ أَنفُسَهُمْ وَأَهْلِيهِمْ يَوْمَ ٱلْقِيَـٰمَةِ ۗ أَلَا ذَٰلِكَ هُوَ ٱلْخُسْرَانُ ٱلْمُبِينُ ﴿١٥﴾

So worship what you will besides Him." Say, "Indeed, the losers are the ones who will lose themselves and their families on the Day of Resurrection. Unquestionably, that is the manifest loss."
