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: "I am commanded to worship God with obedience all-exclusive for Him; 11 I am ordered to be the first of those to be submissive (Muslims to Him)' 12 Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." 13 Proclaim, “I worship only Allah, as His sincere bondman.” 14 Worship besides Him whatever you want. The greatest losers are those whose souls and family members will be lost on the Day of Judgment for this is certainly a great loss". 15 They shall have coverings of Fire, above them and covering (of Fire) beneath them; with this Allah does frighten His slaves: "O My slaves, therefore fear Me!" 16 Those who eschew the serving of idols and turn penitent to God, for them is good tidings! So give thou good tidings to My servants 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 Can you save from the Fire he whom against the word of punishment has been realized? 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 Beholdest thou not that Allah sendeth down water from the heaven, and causeth it to enter springs in the earth, and thereafter produceth thereby corn various coloured. Thereafter it wirhereth, and thou beholdest it turn yellow; then He maketh it chaff. Verily herein is an admonition for men of understanding. 21
