Say: O my servants who believe! be careful of (your duty to) your Lord; for those who do good in this world is good, and Allah's earth is spacious; only the patient will be paid back their reward in full without measure. 10 Say, "I am commanded to worship God and be devoted to His religion 11 And I am commanded that I shall be the first of those who submit. 12 Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." 13 Say: "God alone do I worship, sincere in my faith in Him alone 14 Then worship what ye will beside Him. Say: The losers will be those who lose themselves and their housefolk on the Day of Resurrection. Ah, that will be the manifest loss! 15 Above them will be a covering of fire, below them a cloud (of flames). With this does God warn His creatures: "O My creatures, fear Me." 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 (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 for those who fear displeasing their Lord there are lofty mansions built above mansions, with rivers rippling past below them: A promise of God; (and) God does not go back on His promise. 20 See you not, that Allah sends down water (rain) from the sky, and causes it to penetrate the earth, (and then makes it to spring up) as water-springs and afterward thereby produces crops of different colours, and afterward they wither and you see them turn yellow, then He makes them dry and broken pieces. Verily, in this, is a Reminder for men of understanding. 21
