Tell them: "O my creatures who have come to belief, have fear of displeasing your Lord. There is good for those who do good in this world, and productive is God's earth. Only those who persevere will get their reward measureless." 10 Say (O Muhammad): Lo! I am commanded to worship Allah, making religion pure for Him (only). 11 I am ordered to be the first of those to be submissive (Muslims to Him)' 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 like besides Him. Say (O Muhammad SAW): "The losers are those who will lose themselves and their families on the Day of Resurrection. Verily, that will be a manifest loss!" 15 Clouds of fire will they have above them, and [similar] clouds beneath them…" In this way does God imbue His servants with fear. O you servants of Mine! Be, then, conscious 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 (Muhammad), give the glad news to those of Our servants who listen to the words and only follow the best ones. Tell them that they are those whom God has guided. They are the people of understanding. 18 Is he then on whom is justified the decree of torment - wilt thou rescue him who is in the Fire? 19 But for those who truly feared their Lord, there will be tall mansions, built up storey upon storey, beneath which there will be rivers flowing. This is God's promise: God never fails in His promise. 20 Seest thou not that Allah sends down rain from the sky, and leads it through springs in the earth? Then He causes to grow, therewith, produce of various colours: then it withers; thou wilt see it grow yellow; then He makes it dry up and crumble away. Truly, in this, is a Message of remembrance to men of understanding. 21
