And propound thou unto them the similitude of the life of the world. It is as water which We send down from the heaven, then there mingleth therewith the vegetation of the earth, and lo! it becometh dry stubble which the winds scatter and Allah is over everything potent. 45 Substance and sons are the adornment of the life of the world, and the righteous works that last are excellent with thy Lord in respect of reward, and excellent in respect of hope. 46 And beware a Day whereon we will make the mountains to pass, and thou wilt see the earth away plain, and We shall gather them, and We shall leave of them not one. 47 They shall be brought before your Lord, all lined up, and shall be told: "Now, indeed, you have come before Us in the manner We created you in the first instance, although you thought that We shall not appoint a tryst (with Us)." 48 And the Book shall be placed, then you will see the guilty fearing from what is in it, and they will say: Ah! woe to us! what a book is this! it does not omit a small one nor a great one, but numbers them (all); and what they had done they shall find present (there); and your Lord does not deal unjustly with anyone. 49
