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 thou: verily I am commanded to worship Allah, making for Him religion exclusive. 11 And I am commanded this, in order I may be the first of those who 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, "It is God I serve, sincere in my faith in Him alone -- 14 Then worship what ye will beside Him. Say: The losers will be those who lose themselves and their housefolk on the Day of Resurrection. Ah, that will be 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 There is good news for those who shun the worship of false deities and turn to God, so give good news 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, then, one against whom the decree of Punishment is justly due (equal to one who eschews Evil)? Wouldst thou, then, deliver one (who is) in the Fire? 19 But those who fear their Lord shall have lofty mansions built over one another beneath which rivers flow. This is Allah's promise and never does Allah fail to fulfil His promise. 20 Do you not see that Allah sends down water from the cloud, then makes it go along in the earth in springs, then brings forth therewith herbage of various colors, then it withers so that you see it becoming yellow, then He makes it a thing crushed and broken into pieces? Most surely there is a reminder in this for the men of understanding. 21
