(O Muhammad), warn them of the coming of a Day when We shall bring forth a witness against them from each community and We shall bring you forth as a witness against them all; (and it is for that purpose that) We sent down the Book to you which makes everything clear, and serves as a guidance and mercy and glad tidings to those who have submitted to Allah.
