Say: "[Thus speaks God:] 'O you servants of Mine who have attained to faith! Be conscious of your Sustainer! Ultimate good awaits those who persevere in doing good in this world. And [remember:] wide is God's earth, [and,] verily, they who are patient in adversity will be given their reward in full, beyond all reckoning!'" 10 Tell them, (O Prophet): “I am bidden to serve Allah, consecrating my devotion to Him, 11 and I am bidden to be the first of those who surrender to Him.” 12 Say: I fear, if I disobey my Lord, the chastisement of a grievous day. 13 Say: 'God I serve, making my religion His sincerely; 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 Clouds of fire will they have above them, and [similar] clouds beneath them…" In this way does God imbue His servants with fear. O you servants of Mine! Be, then, conscious of 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 Then, is one who has deserved the decree of punishment [to be guided]? Then, can you save one who is in the Fire? 19 But (as for) those who are careful of (their duty to) their Lord, they shall have high places, above them higher places, built (for them), beneath which flow rivers; (this is) the promise of Allah: Allah will not fail in (His) promise. 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
