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: "Verily, I am commanded to serve Allah with sincere devotion; 11 and I am bidden to be foremost among those who surrender themselves unto God." 12 Say, "I am afraid that for disobeying my Lord I shall suffer the torment of the great day". 13 Say, "It is God I serve, sincere in my faith in Him alone -- 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 coverings beneath them; with that Allah makes His servants to fear, so be careful of (your duty to) Me, O My servants! 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 heed attentively and follow the best from it; it is these whom Allah has guided, and it is these who have intelligence. 18 Is, then, one against whom the decree of Punishment is justly due (equal to one who eschews Evil)? Wouldst thou, then, deliver one (who is) in the Fire? 19 But (as for) those who are careful of (their duty to) their Lord, they shall have high places, above them higher places, built (for them), beneath which flow rivers; (this is) the promise of Allah: Allah will not fail in (His) promise. 20 Have you not seen that God has sent down water from the sky and made it flow as springs out of the earth? He makes crops of different colors grow with this water and flourish, which then turn yellow and wither away. In this there is a reminder for the people of understanding. 21
