النحل — An-Nahl Ayat 89
وَيَوْمَ نَبْعَثُ فِيْ كُلِّ اُمَّةٍ شَهِيْدًا عَلَيْهِمْ مِّنْ اَنْفُسِهِمْ وَجِئْنَا بِكَ شَهِيْدًا عَلٰى هٰٓؤُلَاۤءِۗ وَنَزَّلْنَا عَلَيْكَ الْكِتٰبَ تِبْيَانًا لِّكُلِّ شَيْءٍ وَّهُدًى وَّرَحْمَةً وَّبُشْرٰى لِلْمُسْلِمِيْنَ ࣖ
Wa yauma nab‘aṡu fī kulli ummatin syahīdan ‘alaihim min anfusihim wa ji'nā bika syahīdan ‘alā hā'ulā'(i), wa nazzalnā ‘alaikal-kitāba tibyānal likulli syai'iw wa hudaw wa raḥmataw wa busyrā lil-muslimīn(a).
"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."
