Say, "[God says] O My servants who have believed, fear your Lord. For those who do good in this world will have a good reward -- and God's earth is spacious. Truly, those who persevere patiently will be requited without measure." 10 Say [O Muhammad]: "Behold, I am bidden to worship God, sincere in my faith in Him alone; 11 "And I am commanded (this) in order that I may be the first of those who submit themselves to Allah (in Islam) as Muslims." 12 Say: Lo! if I should disobey my Lord, I fear the doom of a tremendous Day. 13 Say, "I worship God alone and devote myself to His religion. 14 (As for yourselves) worship what you will, other than Him' Say: 'The losers are surely those who lose themselves and their families on the Day of Resurrection. Is that not a 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 There are happy tidings for those who keep away from the worship of false gods and turn to God in repentance. Give glad tidings to My creatures. 17 Those who listen to the word, then follow the best of it; those are they whom Allah has guided, and those it is who are the men of understanding. 18 What! as for him then against whom the sentence of chastisement is due: What! can you save him who is in the fire? 19 As for those who fear their Lord, there await high mansions above which are built (more) high mansions, beneath which rivers flow, such is the promise of Allah; Allah will not fail 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
