Say: "[Thus speaks God:] 'O you servants of Mine who have attained to faith! Be conscious of your Sustainer! Ultimate good awaits those who persevere in doing good in this world. And [remember:] wide is God's earth, [and,] verily, they who are patient in adversity will be given their reward in full, beyond all reckoning!'" 10 Say (O Muhammad): Lo! I am commanded to worship Allah, making religion pure for Him (only). 11 And I am commanded this, in order I may be the first of those who submit. 12 Say: Lo! if I should disobey my Lord, I fear the doom of a tremendous Day. 13 Say: 'I worship Allah and make my religion sincerely His. 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 They shall have coverings of Fire, above them and covering (of Fire) beneath them; with this Allah does frighten His slaves: "O My slaves, therefore 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 listen to speech and follow the best of it. Those are the ones Allah has guided, and those are people of understanding. 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 for those who fear displeasing their Lord there are lofty mansions built above mansions, with rivers rippling past below them: A promise of God; (and) God does not go back on His promise. 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
