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 that I should serve Allah, being sincere to Him in obedience. 11 I am ordered to be the first of those to be submissive (Muslims to Him)' 12 Say, "I am afraid that for disobeying my Lord I shall suffer the torment of the great day". 13 Say: 'God I serve, making my religion His sincerely; 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 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 (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 Those who listen to the Word [good advice La ilaha ill-Allah (none has the right to be worshipped but Allah) and Islamic Monotheism, etc.] and follow the best thereof (i.e. worship Allah Alone, repent to Him and avoid Taghut, etc.) those are (the ones) whom Allah has guided and those are men of understanding (like Zaid bin 'Amr bin Nufail, Salman Al-Farisi and Abu Dhar Al-Ghifari). [Tafsir Al-Qurtubi, Vol. 12, P. 244] 18 Is he on whom the word of doom is fulfilled (to be helped), and canst thou (O Muhammad) rescue him who is in the Fire? 19 But those who fear Allah and keep their duty to their Lord (Allah), for them are built lofty rooms; one above another under which rivers flow (i.e. Paradise). (This is) the Promise of Allah: and Allah does not fail in (His) Promise. 20 Beholdest thou not that Allah sendeth down water from the heaven, and causeth it to enter springs in the earth, and thereafter produceth thereby corn various coloured. Thereafter it wirhereth, and thou beholdest it turn yellow; then He maketh it chaff. Verily herein is an admonition for men of understanding. 21
