Say (O Muhammad SAW): "O My slaves who believe (in the Oneness of Allah Islamic Monotheism), be afraid of your Lord (Allah) and keep your duty to Him. Good is (the reward) for those who do good in this world, and Allah's earth is spacious (so if you cannot worship Allah at a place, then go to another)! Only those who are patient shall receive their rewards in full, without reckoning." 10 Say, "I have been commanded to serve God, dedicating my worship entirely to Him. 11 "And I am commanded (this) in order that I may be the first of those who submit themselves to Allah (in Islam) as Muslims." 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 So worship what you will besides Him." Say, "Indeed, the losers are the ones who will lose themselves and their families on the Day of Resurrection. Unquestionably, that is the manifest loss." 15 There shall be sheets of fire above them and beneath them. This is the end against which Allah warns His servants. So dread My wrath, O you servants of Mine!” 16 There are happy tidings for those who keep away from the worship of false gods and turn to God in repentance. Give glad tidings to My creatures. 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 But what of him against whom the sentence of punishment is justified? Can you rescue one who is already in the Fire? 19 Those who have fear of their Lord will have lofty mansions built upon mansions beneath which streams flow. It is the promise of God. God does not disregard His promise. 20 Have you not seen how Allah sends down water from the sky and threaded it as springs in the earth? Then, He brings forth plants of various colors, after which they wither, and you see them turning yellow, and then He makes them into broken stubble. Surely, in this there is a reminder for those of understanding. 21
