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 bidden to be the first of those who surrender to Him.” 12 Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." 13 Say: "I worship God with devotion all-exclusive for Him. 14 Worship besides Him whatever you want. The greatest losers are those whose souls and family members will be lost on the Day of Judgment for this is certainly a great 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 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 to those who pay heed to what is said and follow the best of it. They are the ones whom Allah has guided to the Right Way; they are the ones endowed with understanding. 18 Can you save from the Fire he whom against the word of punishment has been realized? 19 But (as for) those who are careful of (their duty to) their Lord, they shall have high places, above them higher places, built (for them), beneath which flow rivers; (this is) the promise of Allah: Allah will not fail in (His) promise. 20 Do you not see that God sends down water from the sky, then makes it flow in rills on the earth, and brings forth corn from it which, having passed through changes of shade and colour, comes to ripen, and you see it autumnal yellow; then He reduces it to chaff. There are indeed lessons in this for those who are wise. 21
