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: 'I am ordered to worship Allah making my religion sincerely His. 11 And I am commanded to 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 Allah I serve, with my sincere (and exclusive) devotion: 14 You may worship what you will apart from Him." Say: "Surely the greatest losers will be those who will lose their own selves and their people on the Day of Resurrection." Remember, this will be an all-too-evident 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 There is good news for those who shun the worship of false deities and turn to God, so give good news 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 What! as for him then against whom the sentence of chastisement is due: What! can you save him who is in the fire? 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 Have you not seen how Allah sends down water from the sky and threaded it as springs in the earth? Then, He brings forth plants of various colors, after which they wither, and you see them turning yellow, and then He makes them into broken stubble. Surely, in this there is a reminder for those of understanding. 21
