Indeed in that is a sign for those who fear the punishment of the Hereafter. That is a Day for which the people will be collected, and that is a Day [which will be] witnessed.

In this there is a sign for the one who fears the punishment of the Hereafter. That is a day when all the people shall be gathered together, and that is a day which will be witnessed by all.
