إِنَّنِي أَنَا اللَّهُ لَا إِلَهَ إِلَّا أَنَا فَاعْبُدْنِي وَأَقِمِ الصَّلَاةَ لِذِكْرِي
[20:14]
Surely I am Allah, there is no god but I, therefore serve Me and keep up prayer for My remembrance:
"Verily, I am Allah: There is no god but I: So serve thou Me (only), and establish regular prayer for celebrating My praise.
Lo! I, even I, am Allah, There is no Allah save Me. So serve Me and establish worship for My remembrance.
