10. After Tauhid, the second thing that was revealed to all the Prophets was the reality of the Hereafter, and they were appointed to impart its knowledge to their peoples. Here its object has also been stated. The Hour of Resurrection is destined to come so that everyone should get the recompense in the Hereafter of what he did in this world, and that Hour has been kept secret to fulfill the requirement of the trial. For the one who believes in the Hereafter will always be on his guard against any deviation from the right way, and the one who does not believe in the coming of that Hour will remain engaged in other things, for he will think that he did not see any sign of the coming of the Hour.
