An-Nahl 16:89

وَيَوۡمَ نَبۡعَثُ فِي كُلِّ أُمَّةٖ شَهِيدًا عَلَيۡهِم مِّنۡ أَنفُسِهِمۡۖ وَجِئۡنَا بِكَ شَهِيدًا عَلَىٰ هَـٰٓؤُلَآءِۚ وَنَزَّلۡنَا عَلَيۡكَ ٱلۡكِتَٰبَ تِبۡيَٰنٗا لِّكُلِّ شَيۡءٖ وَهُدٗى وَرَحۡمَةٗ وَبُشۡرَىٰ لِلۡمُسۡلِمِينَ 89

And [mention] the Day when We will resurrect among every nation a witness over them from themselves. And We will bring you, [O Muhammad], as a witness over your nation. And We have sent down to you the Book as clarification for all things and as guidance and mercy and good tidings for the Muslims
