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 have been commanded to serve God making my religion His sincerely; 11 And I have been commanded to be the first [among you] of the Muslims." 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 so serve what you will apart from Him.' Say: 'Surely the losers are they who lose themselves and their families on the Day of Resurrection; is not that the manifest 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 avoid At-Taghut (false deities) by not worshipping them and turn to Allah in repentance, for them are glad tidings; so announce the good news to My slaves, 17 Who hear advice and follow the best thereof. Such are those whom Allah guideth, and such are men of understanding. 18 Then, is one who has deserved the decree of punishment [to be guided]? Then, can you save one who is in the Fire? 19 But those who keep their duty to their Lord, for them are lofty halls with lofty halls above them, built (for them), beneath which rivers flow. (It is) a promise of Allah. Allah faileth not 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
