Say to My believing servants, "Have fear of your Lord. Those who act righteously in this life will receive good reward. The land of God is vast. God will recompense the deeds of those who have exercised patience, without keeping an account". 10 Say: "Verily, I am commanded to serve Allah with sincere devotion; 11 and I have been commanded to be the first of those that surrender.' 12 Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." 13 Say: "I worship God with devotion all-exclusive for Him. 14 So worship whatsoever ye will, besides him. Say thou: verily the losers are those who shall have lost themselves and their household on the Day of Judgment. Lo! that will be a loss manifest. 15 They will have sheets of fire above them and sheets of fire beneath them." That is how God puts fear into the hearts of His servants. Fear me, then, My servants. 16 Those who shun the worship of idols and turn in repentance to Allah for them glad tidings. Therefore give good tidings to My worshipers, 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 What! as for him then against whom the sentence of chastisement is due: What! can you save him who is in the fire? 19 As against this they who of their Sustainer are conscious shall [in the life to come] have mansions raised upon mansions high, beneath which running waters flow: [this is] God's promise - [and] never does God fail to fulfill His promise. 20 Do you not see that Allah sends down rain from the sky and makes it flow as springs [and rivers] in the earth; then He produces thereby crops of varying colors; then they dry and you see them turned yellow; then He makes them [scattered] debris. Indeed in that is a reminder for those of understanding. 21
