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 I am ordered to be the first of those to be submissive (Muslims to Him)' 12 Say thou: verily I fear, if I disobeyed my Lord, torment of a Day mighty. 13 Say: "It is Allah I serve, with my sincere (and exclusive) devotion: 14 Serve then what you like besides Him. Say: The losers surely are those who shall have lost themselves and their families on the day of resurrection; now surely that is the clear loss. 15 Above and below them their will be shadows of fire. This is how God frightens His servants. My servants have fear of Me. 16 And those who put away false gods lest they should worship them and turn to Allah in repentance, for them there are glad tidings. Therefor give good tidings (O Muhammad) to My bondmen 17 who listen to the Words and follow what is finest of it. These are they whom Allah has guided. They are those of understanding. 18 (O Prophet), can you save him (from chastisement) against whom the sentence of chastisement has become due; him who has, (as it were), already fallen into the Fire?” 19 But it is for those who fear their Lord. That lofty mansions, one above another, have been built: beneath them flow rivers (of delight): (such is) the Promise of Allah: never doth Allah fail in (His) promise. 20 Do you not see that Allah sends down rain from the sky and makes it flow as springs [and rivers] in the earth; then He produces thereby crops of varying colors; then they dry and you see them turned yellow; then He makes them [scattered] debris. Indeed in that is a reminder for those of understanding. 21
