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: "Verily, I am commanded to serve Allah with sincere devotion; 11 And I am commanded that I shall 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 God I serve, sincere in my faith in Him alone -- 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 They will have canopies of fire above them and below them, canopies. By that Allah threatens His servants. O My servants, then fear Me. 16 seeing that for those who shun the powers of evil lest they [be tempted to] worship them, and turn unto God instead, there is the glad tiding [of happiness in the life to come]. Give, then, this glad tiding to [those of] My servants 17 (Muhammad), give the glad news to those of Our servants who listen to the words and only follow the best ones. Tell them that they are those whom God has guided. They are the people 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 for those who truly feared their Lord, there will be tall mansions, built up storey upon storey, beneath which there will be rivers flowing. This is God's promise: God never fails in 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
