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 Say: I am commanded that I should serve Allah, being sincere to Him in obedience. 11 I am ordered to be the first of those to be submissive (Muslims to Him)' 12 Say, "I fear, if I disobey my Lord, the punishment of a Terrible Day." 13 Say thou: it is Allah I worship, making for Him my religion exclusive 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 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 for those who truly feared their Lord, there will be tall mansions, built up storey upon storey, beneath which there will be rivers flowing. This is God's promise: God never fails in His promise. 20 Hast thou not seen how Allah hath sent down water from the sky and hath caused it to penetrate the earth as watersprings, and afterward thereby produceth crops of divers hues; and afterward they wither and thou seest them turn yellow; then He maketh them chaff. Lo! herein verily is a reminder for men of understanding. 21
