(12) And Moses chose of his people seventy men for Our appointed tryst and, when the trembling came on them, he said: My Lord! If Thou hadst willed Thou hadst destroyed them long before, and me with them. Wilt thou destroy us for that which the ignorant among us did? It is but Thy trial (of us).

(13) And ordain for us in this world that which is good, and in the Hereafter (that which is good), Lo! We have turned unto Thee. He said: I smite with My punishment whom I will, and My mercy embraceth all things, therefore I shall ordain it for those who ward off (evil) and pay the poor-due, and those who believe Our revelations;

He is the Best of Judges.

(18) Look, therefore, at the prints of Allah's mercy (in creation): how He quickeneth the earth after her death. Lo! He verily is the Quickener of the Dead, and He is Able to do all things.

(19) But they said: Our Lord! Make the stage between our journeys longer. And they wronged themselves, therefore We made them bywords (in the land) and scattered them abroad, a total scattering. Lo! herein verily are portents for each steadfast, grateful (heart).
