An-Nahl - ১৬:৮৯

وَيَوْمَ نَبْعَثُ فِي كُلِّ أُمَّةٍ شَهِيدًا عَلَيْهِم مِّنْ أَنفُسِهِمْ وَجِئْنَا بِكَ شَهِيدًا عَلَى هَـؤُلاء وَنَزَّلْنَا عَلَيْكَ الْكِتَابَ تِبْيَانًا لِّكُلِّ شَيْءٍ وَهُدًى وَرَحْمَةً وَبُشْرَى لِلْمُسْلِمِينَ
[16:89]
And on the day when We will raise up in every people a witness against them from among themselves, and bring you as a witness against these-- and We have revealed the Book to you explaining clearly everything, and a guidance and mercy and good news for those who submit.
One day We shall raise from all Peoples a witness against them, from amongst themselves: and We shall bring thee as a witness against these (thy people): and We have sent down to thee the Book explaining all things, a Guide, a Mercy, and Glad Tidings to Muslims.
And (bethink you of) the day when We raise in every nation a witness against them of their own folk, and We bring thee (Muhammad) as a witness against these. And We reveal the Scripture unto thee as an exposition of all things, and a guidance and a mercy and good tidings for those who have surrendered (to Allah).
