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 with obedience all-exclusive for Him; 11 And I am commanded to be the first of those who submit." 12 Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." 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 them they shall have overshadowings. of the Fire, and underneath them overshadowings; that it is wherewith God frightens His servants: "O My servants, so fear you Me!"' 16 Those who have avoided worshipping idols and have turned in repentance to God will receive the glad news. 17 who listen to what is said and follow what is best in it. These are the ones God has guided; these are the people endowed with understanding. 18 Can you save from the Fire he whom against the word of punishment has been realized? 19 But those who have feared their Lord - for them are chambers, above them chambers built high, beneath which rivers flow. [This is] the promise of Allah. Allah does not fail in [His] promise. 20 Do you not see that Allah sends down water from the cloud, then makes it go along in the earth in springs, then brings forth therewith herbage of various colors, then it withers so that you see it becoming yellow, then He makes it a thing crushed and broken into pieces? Most surely there is a reminder in this for the men of understanding. 21
