(Lo! Herein) in that which We mentioned to you (verily there is a portent) a lesson (for those who fear the doom of the Hereafter) such that they do not follow in their footsteps. (That is a day) the Day of Resurrection (unto which mankind will be gathered) the first and last among mankind will be gathered, (and that is a day that will be witnessed) it will be witnessed by the dwellers of heaven and earth.
