Surat Ar-Ra'd (The Thunder) - الرعد

كَذَٰلِكَ أَرْسَلْنَٰكَ فِىٓ أُمَّةٍ قَدْ خَلَتْ مِن قَبْلِهَآ أُمَمٌ لِّتَتْلُوَا۟ عَلَيْهِمُ ٱلَّذِىٓ أَوْحَيْنَآ إِلَيْكَ وَهُمْ يَكْفُرُونَ بِٱلرَّحْمَٰنِ قُلْ هُوَ رَبِّى لَآ إِلَٰهَ إِلَّا هُوَ عَلَيْهِ تَوَكَّلْتُ وَإِلَيْهِ مَتَابِ ﴿٣٠﴾

And thus We have sent you among a nation before which other nations have passed away, that you might recite to them what We have revealed to you and (still) they deny the Beneficent Allah. Say: He is my Lord, there is no god but He; on Him do I rely and to Him is my return.
