Every Prophet will bear Witness against his Nation on the Day of Resurrection

Allah addressed His servant and Messenger Muhammad , saying:

﴿ وَيَوۡمَ نَبۡعَثُ فِى كُلِّ أُمَّةٍ۬ شَهِيدًا عَلَيۡهِم مِّنۡ أَنفُسِہِمۡ‌ۖ وَجِئۡنَا بِكَ شَہِيدًا عَلَىٰ هَـٰٓؤُلَآءِ‌ۚ ﴾

(And on the Day when We resurrect a witness from each nation from among themselves, and We bring you (O Muhammad) as a witness against these.), meaning, your Ummah. The Ayah means: remember that Day and its terrors, and the great honor and high position that Allah has bestowed upon you. This Ayah is like the Ayah with which `Abdullah bin Mas`ud ended when he recited to the Messenger of Allah from the beginning of Surat An-Nisa'. When he reached the Ayah:

﴿ فَكَيۡفَ إِذَا جِئۡنَا مِن كُلِّ أُمَّةِۭ بِشَهِيدٍ۬ وَجِئۡنَا بِكَ عَلَىٰ هَـٰٓؤُلَآءِ شَہِيدً۬ا ﴾

(How (will it be) then, when We bring from each nation a witness and We bring you (O Muhammad) as a witness against these) (4:41) the Messenger of Allah said to him:

« حَسْبُك »

(Enough.) Ibn Mas`ud said: "I turned to him and saw his eyes streaming with tears.''
