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 thou: verily I am commanded to worship Allah, making for Him religion exclusive. 11 and I am commanded to be the first Muslim". 12 Say: "I would, if I disobeyed my Lord, indeed have fear of the Penalty of a Mighty Day." 13 Say: "It is Allah I serve, with my sincere (and exclusive) devotion: 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 They shall have coverings of fire above them and coverings beneath them; with that Allah makes His servants to fear, so be careful of (your duty to) Me, O My servants! 16 Those who avoid At-Taghut (false deities) by not worshipping them and turn to Allah in repentance, for them are glad tidings; so announce the good news to My slaves, 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). [Tafsir Al-Qurtubi, Vol. 12, P. 244] 18 So will the one upon whom the Word of punishment has proved true, ever be equal to those who are forgiven? So will you guide and save the one who deserves the fire? (Because the hearts of some disbelievers are sealed). 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 Did you not see that it is Allah Who sent down water from the sky, and then with it made springs in the earth, and then with it produces crops of various colours, and then it dries up and you see it has become yellow, and He then fragments them into small pieces; indeed in this is a reminder for people of intellect. 21
