Say: O my servants who believe! be careful of (your duty to) your Lord; for those who do good in this world is good, and Allah's earth is spacious; only the patient will be paid back their reward in full without measure. 10 Say: "Verily, I am commanded to serve Allah with sincere devotion; 11 And I have been commanded to be the first [among you] of the Muslims." 12 Say, "I fear, if I disobey my Lord, the punishment of a Terrible Day." 13 Say: Allah (it is Whom) I serve, being sincere to Him in my obedience: 14 So worship what you will besides Him." Say, "Indeed, the losers are the ones who will lose themselves and their families on the Day of Resurrection. Unquestionably, that is the manifest loss." 15 Above and below them their will be shadows of fire. This is how God frightens His servants. My servants have fear of 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 Can he against whom the sentence of punishment has been justified (be rescued)? Can you save him who is in the Fire? 19 As for those who fear their Lord, there await high mansions above which are built (more) high mansions, beneath which rivers flow, such is the promise of Allah; Allah will not fail His promise. 20 Do you not see that God sends down water from the sky, then makes it flow in rills on the earth, and brings forth corn from it which, having passed through changes of shade and colour, comes to ripen, and you see it autumnal yellow; then He reduces it to chaff. There are indeed lessons in this for those who are wise. 21
