Say to My believing servants, "Have fear of your Lord. Those who act righteously in this life will receive good reward. The land of God is vast. God will recompense the deeds of those who have exercised patience, without keeping an account". 10 Say, [O Muhammad], "Indeed, I have been commanded to worship Allah, [being] sincere to Him in religion. 11 "And I am commanded (this) in order that I may be the first of those who submit themselves to Allah (in Islam) as Muslims." 12 Say: Lo! if I should disobey my Lord, I fear the doom of a tremendous Day. 13 Say thou: it is Allah I worship, making for Him my religion exclusive 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 sheets of fire above them and sheets of fire beneath them." That is how God puts fear into the hearts of His servants. Fear me, then, My servants. 16 And those who stayed away from the worship of idols, and inclined towards Allah – for them are glad tidings; therefore give glad tidings to My bondmen. – 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 it is for those who fear their Lord. That lofty mansions, one above another, have been built: beneath them flow rivers (of delight): (such is) the Promise of Allah: never doth Allah fail in (His) promise. 20 Do you not see that Allah sent down water from the sky, then made it flow on earth as springs and streams and rivers and then with it He brings forth vegetation of various hues; then this vegetation ripens and dries up, turning yellow, whereafter He reduces it to broken straw? Surely there is a lesson in this for those endowed with understanding. 21
