Say: O My bondmen who believe! Observe your duty to your Lord. For those who do good in this world there is good, and Allah's earth is spacious. Verily the steadfast will be paid their wages without stint. 10 Say, "I have been commanded to serve God, dedicating my worship entirely to Him. 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 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 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 Those who eschew the serving of idols and turn penitent to God, for them is good tidings! So give thou 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 Can he against whom the sentence of punishment has been justified (be rescued)? Can you save him who is in the Fire? 19 But for those who fear their Lord, are the high chambers with more high chambers built above them – rivers flowing beneath them; a promise of Allah; Allah does not renege on His promise. 20 Seest thou not that Allah sends down rain from the sky, and leads it through springs in the earth? Then He causes to grow, therewith, produce of various colours: then it withers; thou wilt see it grow yellow; then He makes it dry up and crumble away. Truly, in this, is a Message of remembrance to men of understanding. 21
