Say: 'My servants who believe, fear your Lord. For those who do good in this world good, and God's earth is wide. Surely the patient will be paid their wages in full without reckoning.' 10 Say (O Muhammad SAW): "Verily, I am commanded to worship Allah (Alone) by obeying Him and doing religious deeds sincerely for Allah's sake only and not to show off, and not to set up rivals with Him in worship; 11 and I am bidden to be foremost among those who surrender themselves unto God." 12 Say: "Behold, I would dread, were I to rebel against my Sustainer, the suffering [which would befall me] on that awesome Day [of Judgment]." 13 Say: “Allah alone shall I serve, consecrating my devotion to Him. 14 So serve, apart from Him, whomsoever you please.” Say: “Behold, the real losers shall be those who will have lost their own selves and their kith and kin on the Day of Resurrection. Behold, that is the obvious loss. 15 They shall have coverings of fire above them and coverings beneath them; with that Allah makes His servants to fear, so be careful of (your duty to) Me, O My servants! 16 Those who have avoided worshipping idols and have turned in repentance to God will receive the glad news. 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 Is he then on whom is justified the decree of torment - wilt thou rescue him who is in the Fire? 19 But those who fear Allah and keep their duty to their Lord (Allah), for them are built lofty rooms; one above another under which rivers flow (i.e. Paradise). (This is) the Promise of Allah: and Allah does not fail in (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
