In the name of Allah, Most Gracious, Most Merciful.
20. Know that the life of this world is only play and amusement, pomp and mutual boasting among you, and rivalry in respect of wealth and children, as the likeness of vegetation after rain, thereof the growth is pleasing to the tiller; afterwards it dries up and you see it turning yellow; then it becomes straw. But in the Hereafter (there is) a severe torment (for the disbelievers, evil-doers), and (there is) Forgiveness from Allâh and (His) Good Pleasure (for the believers, good-doers), whereas the life of this world is only a deceiving enjoyment.
21. Race one with another in hastening towards Forgiveness from your Lord (Allâh), and towards Paradise, the width whereof is as the width of heaven and earth, prepared for those who believe in Allâh and His Messengers. That is the Grace of Allâh which He bestows on whom He pleases. And Allâh is the Owner of Great Bounty.
22. No calamity befalls on the earth or in yourselves but is inscribed in the Book of Decrees (Al-Lauh Al-Mahfûz), before We bring it into existence. Verily, that is easy for Allâh.
23. In order that you may not be sad over matters that you fail to get, nor rejoice because of that which has been given to you. And Allâh likes not prideful boasters.
