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 have been commanded to serve God, dedicating my worship entirely to Him. 11 And I am commanded to be the first of those who submit." 12 Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." 13 Say, "It is God I serve, sincere in my faith in Him alone -- 14 Serve then what you like besides Him. Say: The losers surely are those who shall have lost themselves and their families on the day of resurrection; now surely that is the clear loss. 15 For them! above them shall be coverings of Fire and beneath them coverings. Therewith Allah affrighteth His bondmen. O My bondmen! wherefore fear Me. 16 And those who stayed away from the worship of idols, and inclined towards Allah – for them are glad tidings; therefore give glad tidings to My bondmen. – 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 (O Prophet), can you save him (from chastisement) against whom the sentence of chastisement has become due; him who has, (as it were), already fallen into the Fire?” 19 But those who fear their Lord, for them are lofty chambers with lofty chambers above them, built whereunder rivers flow: the promise of Allah, and Allah faileth not the appointment. 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
