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 have been commanded to serve God, dedicating my worship entirely to Him. 11 and I have been commanded to be the first of those that surrender.' 12 Say: 'Indeed, if I rebel against my Lord I fear the punishment of a dreadful Day' 13 Say: 'God I serve, making my religion His sincerely; 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 For them! above them shall be coverings of Fire and beneath them coverings. Therewith Allah affrighteth His bondmen. O My bondmen! wherefore fear Me. 16 Those who shun the worship of idols and turn in repentance to Allah for them glad tidings. Therefore give good tidings to My worshipers, 17 Who hearken unto the word and follow that which is the excellent thereof. These are they whom Allah hath guided, and those are men of understanding. 18 On the other hand, could one on whom [God's] sentence of suffering has been passed [be rescued by man]? Couldst thou, perchance, save one who is [already, as it were,] in the fire? 19 As for those who fear their Lord, there await high mansions above which are built (more) high mansions, beneath which rivers flow, such is the promise of Allah; Allah will not fail His promise. 20 Seest thou not that Allah sends down rain from the sky, and leads it through springs in the earth? Then He causes to grow, therewith, produce of various colours: then it withers; thou wilt see it grow yellow; then He makes it dry up and crumble away. Truly, in this, is a Message of remembrance to men of understanding. 21
