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: "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 fear, if I disobey my Lord, the punishment of a Terrible Day." 13 Say: "I worship God with devotion all-exclusive for Him. 14 Serve then what you like besides Him. Say: The losers surely are those who shall have lost themselves and their families on the day of resurrection; now surely that is the clear loss. 15 They have an awning of fire above them and beneath them a dais (of fire). With this doth Allah appal His bondmen. O My bondmen, therefor fear 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 listen to the Words and follow what is finest of it. These are they whom Allah has guided. They are those 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 Those who have fear of their Lord will have lofty mansions built upon mansions beneath which streams flow. It is the promise of God. God does not disregard 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
