﴿ فَكَيْفَ إِذَا جِئْنَا مِن كُلِّ أُمَّةٍۭ بِشَهِيدٍۢ وَجِئْنَا بِكَ عَلَىٰ هَٰٓؤُلَآءِ شَهِيدًۭا ﴾

“How, then, [will the sinners fare on Judgment Day,] when We shall bring forward witnesses from within every community, and bring thee [O Prophet] as witness against them?”

(But how (will it be with them)) how shall the unbelievers react (when we bring of every people a witness) a prophet who will testify that he has delivered the message to them, (and We bring thee) O Muhammad (a witness against these?) it is also said that this means: We bring you, O Muhammad, a witness in favour of your Community, testifying that it is reliable and upright. This is because his Community will be a witness for the other prophets against their nations when the latter will deny having received any message from them.
