Tell them: "O my creatures who have come to belief, have fear of displeasing your Lord. There is good for those who do good in this world, and productive is God's earth. Only those who persevere will get their reward measureless." 10 Say, "I am commanded to worship God and be devoted to His religion 11 And I am commanded that I shall be the first of those who submit. 12 Say, "I fear, if I disobey my Lord, the punishment of a Terrible Day." 13 Say: "God alone do I worship, sincere in my faith in Him alone 14 so serve what you will apart from Him.' Say: 'Surely the losers are they who lose themselves and their families on the Day of Resurrection; is not that the manifest loss? 15 Above them will be a covering of fire, below them a cloud (of flames). With this does God warn His creatures: "O My creatures, fear Me." 16 And those who avoid the devils lest they should worship them and turn unto Allah in penitence, for them are glad tidings. Wherefore give thou glad tidings unto My bondmen, 17 Those who heed attentively and follow the best from it; it is these whom Allah has guided, and it is these who have intelligence. 18 Then, is one who has deserved the decree of punishment [to be guided]? Then, can you save one who is in the Fire? 19 But those who fear their Lord shall have lofty mansions built over one another beneath which rivers flow. This is Allah's promise and never does Allah fail to fulfil His promise. 20 Beholdest thou not that Allah sendeth down water from the heaven, and causeth it to enter springs in the earth, and thereafter produceth thereby corn various coloured. Thereafter it wirhereth, and thou beholdest it turn yellow; then He maketh it chaff. Verily herein is an admonition for men of understanding. 21
