إِنَّ هَذِهِ أُمَّتُكُمْ أُمَّةً وَاحِدَةً وَأَنَا رَبُّكُمْ فَاعْبُدُونِ
[21:92]
Surely this Islam is your religion, one religion (only), and I am your Lord, therefore serve Me.
Verily, this brotherhood of yours is a single brotherhood, and I am your Lord and Cherisher: therefore serve Me (and no other).
Lo! this, your religion, is one religion, and I am your Lord, so worship Me.
