وَيَوْمَ نَبْعَثُ فِى كُلِّ أُمَّةٍ شَهِيدًا عَلَيْهِم مِّنْ أَنفُسِهِمْ ۖ وَجِئْنَا بِكَ شَهِيدًا عَلَىٰ هَـٰٓؤُلَآءِ ۚ وَنَزَّلْنَا عَلَيْكَ ٱلْكِتَـٰبَ تِبْيَـٰنًا لِّكُلِّ شَىْءٍ وَهُدًى وَرَحْمَةً وَبُشْرَىٰ لِلْمُسْلِمِينَ ٨٩
And [mention] the Day when We will resurrect among every nation a witness over them from themselves [i.e., their prophet]. And We will bring you, [O Muḥammad], as a witness over these [i.e., 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.
