Say: "O ye my servants who believe! Fear your Lord, good is (the reward) for those who do good in this world. Spacious is Allah's earth! those who patiently persevere will truly receive a reward 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, "It is God I serve, sincere in my faith in Him alone -- 14 so serve what you will apart from Him.' Say: 'Surely the losers are they who lose themselves and their families on the Day of Resurrection; is not that the manifest loss? 15 Above them they shall have layers of fire and beneath them layers. By this Allah puts fear into His worshipers' 'O My worshipers, fear 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 So will the one upon whom the Word of punishment has proved true, ever be equal to those who are forgiven? So will you guide and save the one who deserves the fire? (Because the hearts of some disbelievers are sealed). 19 But those who fear their Lord, for them are lofty chambers with lofty chambers above them, built whereunder rivers flow: the promise of Allah, and Allah faileth not the appointment. 20 Did you not see that it is Allah Who sent down water from the sky, and then with it made springs in the earth, and then with it produces crops of various colours, and then it dries up and you see it has become yellow, and He then fragments them into small pieces; indeed in this is a reminder for people of intellect. 21
