Say: 'My worshipers who believe, fear your Lord. For those who do good in this world there is good and the earth of Allah is wide; surely, those who are patient will be recompensed in full without count' 10 Say [O Muhammad]: "Behold, I am bidden to worship God, sincere in my faith in Him alone; 11 I have been commanded to be the first to submit." 12 Say: "Behold, I would dread, were I to rebel against my Sustainer, the suffering [which would befall me] on that awesome Day [of Judgment]." 13 Say: "I worship God with devotion all-exclusive for Him. 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 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 (On the other hand), good tidings await those who eschew serving false gods and penitently return to Allah. (O Prophet), give good tidings to My servants, 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 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 But for those who fear displeasing their Lord there are lofty mansions built above mansions, with rivers rippling past below them: A promise of God; (and) God does not go back on His promise. 20 Have you not seen how Allah sends down water from the sky and threaded it as springs in the earth? Then, He brings forth plants of various colors, after which they wither, and you see them turning yellow, and then He makes them into broken stubble. Surely, in this there is a reminder for those of understanding. 21
