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 have been commanded to serve God making my religion His sincerely; 11 and I have been commanded to be the first of those that surrender.' 12 Say: I fear, if I disobey my Lord, the chastisement of a grievous day. 13 Say: Allah I worship, making my religion pure for Him (only). 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 They will have canopies of fire above them and below them, canopies. By that Allah threatens His servants. O My servants, then fear Me. 16 And (as for) those who keep off from the worship of the idols and turn to Allah, they shall have good news, therefore give good news to My servants, 17 Who hearken unto the word and follow that which is the excellent thereof. These are they whom Allah hath guided, and those are men of understanding. 18 Then, is one who has deserved the decree of punishment [to be guided]? Then, can you save one 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 Beholdest thou not that Allah sendeth down water from the heaven, and causeth it to enter springs in the earth, and thereafter produceth thereby corn various coloured. Thereafter it wirhereth, and thou beholdest it turn yellow; then He maketh it chaff. Verily herein is an admonition for men of understanding. 21
