Tell them (O Prophet): “O you servants of Mine who believe, have fear of your Lord. A good end awaits those who did good in this world. Allah's earth is spacious. Verily those who persevere shall be granted their reward 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 thou: verily I fear, if I disobeyed my Lord, torment of a Day mighty. 13 Say, "I worship God alone and devote myself to His religion. 14 Then worship what ye will beside Him. Say: The losers will be those who lose themselves and their housefolk on the Day of Resurrection. Ah, that will be the manifest loss! 15 Above and below them their will be shadows of fire. This is how God frightens His servants. My servants have fear of Me. 16 And those who avoid the devils lest they should worship them and turn unto Allah in penitence, for them are glad tidings. Wherefore give thou glad tidings unto My bondmen, 17 Who hear advice and follow the best thereof. Such are those whom Allah guideth, and such are men of understanding. 18 He against whom the word of chastisement is realized -- shalt thou deliver him out of the Fire? 19 But those who have feared their Lord - for them are chambers, above them chambers built high, beneath which rivers flow. [This is] the promise of Allah. Allah does 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
