وَإِنَّ هَذِهِ أُمَّتُكُمْ أُمَّةً وَاحِدَةً وَأَنَا رَبُّكُمْ فَاتَّقُونِ
[23:52]
And surely this your religion is one religion and I am your Lord, therefore be careful (of your duty) to Me.
And verily this Brotherhood of yours is a single Brotherhood, and I am your Lord and Cherisher: therefore fear Me (and no other).
And lo! this your religion is one religion and I am your Lord, so keep your duty unto Me.
