Say: "O ye my servants who believe! Fear your Lord, good is (the reward) for those who do good in this world. Spacious is Allah's earth! those who patiently persevere will truly receive a reward without measure!" 10 Say: 'I have been commanded to serve God making my religion His sincerely; 11 And I have been commanded to be the first [among you] of the Muslims." 12 Say: "I would, if I disobeyed my Lord, indeed have fear of the Penalty of a Mighty Day." 13 Say (O Muhammad SAW) "Allah Alone I worship by doing religious deeds sincerely for His sake only and not to show-off, and not to set up rivals with Him in worship." 14 “Therefore you can worship what you want besides Him!” Say, “The worst losers are those who will lose themselves and their household on the Day of Resurrection; pay heed! This is the plain loss!” 15 Above them are mountains of fire and beneath them are mountains of fire; Allah scares His bondmen with this; “O My bondmen! Fear Me!” 16 And those who put away false gods lest they should worship them and turn to Allah in repentance, for them there are glad tidings. Therefor give good tidings (O Muhammad) 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 await lofty chambers, above which are built lofty chambers, underneath which rivers flow -- God's promise; God fails not the tryst. 20 Have you not seen that God has sent down water from the sky and made it flow as springs out of the earth? He makes crops of different colors grow with this water and flourish, which then turn yellow and wither away. In this there is a reminder for the people of understanding. 21
