Quran 16:89 from Surah An-Nahl on Divine Marvels.
وَيَوۡمَ نَبۡعَثُ فِي كُلِّ أُمَّةٖ شَهِيدًا عَلَيۡهِم مِّنۡ أَنفُسِهِمۡۖ وَجِئۡنَا بِكَ شَهِيدًا عَلَىٰ هَٰٓؤُلَآءِۚ وَنَزَّلۡنَا عَلَيۡكَ ٱلۡكِتَٰبَ تِبۡيَٰنٗا لِّكُلِّ شَيۡءٖ وَهُدٗى وَرَحۡمَةٗ وَبُشۡرَىٰ لِلۡمُسۡلِمِينَ
English translation: And the Day We will resurrect among every nation a witness over them from themselves And We (will) bring you (as) a witness over these And We sent down to you the Book (as) a clarification of every thing and a guidance and mercy and glad tidings for the Muslims
Transliteration: wayawma nab'athu fi kulli ummatin shahidan alayhim min anfusihim waji'na bika shahidan ala haulai wanazzalna alayka al-kitaba tib'yanan likulli shayin wahudan warahmatan wabush'ra lil'mus'limina
