Indeed, I am Allah. There is no deity except Me, so worship Me and establish prayer for My remembrance.
The Saheeh International Quran Translation
إِنَّنِىٓ أَنَا ٱللَّهُ لَآ إِلَٰهَ إِلَّآ أَنَا۠ فَٱعْبُدْنِى وَأَقِمِ ٱلصَّلَوٰةَ لِذِكْرِىٓIndeed, I am Allah. There is no deity except Me, so worship Me and establish prayer for My remembrance.
