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: 'I have been commanded to serve God making my religion His sincerely; 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 as for yourselves, worship anything you please besides Him!" Say, "The real losers will be those who lose themselves and all their kith and kin on the Day of Resurrection. That is the [most] obvious loss. 15 Above them are mountains of fire and beneath them are mountains of fire; Allah scares His bondmen with this; “O My bondmen! Fear Me!” 16 Those who shun the worship of idols and turn in repentance to Allah for them glad tidings. Therefore give good tidings to My worshipers, 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 for those who truly feared their Lord, there will be tall mansions, built up storey upon storey, beneath which there will be rivers flowing. This is God's promise: God never fails in His promise. 20 Have you not seen that God has sent down water from the sky and made it flow as springs out of the earth? He makes crops of different colors grow with this water and flourish, which then turn yellow and wither away. In this there is a reminder for the people of understanding. 21
