Say: 'My servants who believe, fear your Lord. For those who do good in this world good, and God's earth is wide. Surely the patient will be paid their wages in full without reckoning.' 10 Say: "Verily, I am commanded to serve Allah with sincere devotion; 11 "And I am commanded (this) in order that I may be the first of those who submit themselves to Allah (in Islam) as Muslims." 12 Say, "I fear, if I disobey my Lord, the punishment of a Terrible Day." 13 Say: 'I worship Allah and make my religion sincerely His. 14 "Serve ye what ye will besides him." Say: "Truly, those in loss are those who lose their own souls and their People on the Day of Judgment: Ah! that is indeed the (real and) evident Loss! 15 Above them will be a covering of fire, below them a cloud (of flames). With this does God warn His creatures: "O My creatures, fear Me." 16 Those who have avoided worshipping idols and have turned in repentance to God will receive the glad news. 17 Those who listen to the Word [good advice La ilaha ill-Allah (none has the right to be worshipped but Allah) and Islamic Monotheism, etc.] and follow the best thereof (i.e. worship Allah Alone, repent to Him and avoid Taghut, etc.) those are (the ones) whom Allah has guided and those are men of understanding (like Zaid bin 'Amr bin Nufail, Salman Al-Farisi and Abu Dhar Al-Ghifari).

[This is] the promise of Allah. Allah does not fail in [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
