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: "Verily, I am commanded to serve Allah with sincere devotion; 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: "It is Allah I serve, with my sincere (and exclusive) devotion: 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 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 avoid At-Taghut (false deities) by not worshipping them and turn to Allah in repentance, for them are glad tidings; so announce the good news to My slaves, 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 on whom the word of doom is fulfilled (to be helped), and canst thou (O Muhammad) rescue him who is in the Fire? 19 But those who fear their Lord shall have lofty mansions built over one another beneath which rivers flow. This is Allah's promise and never does Allah fail to fulfil His promise. 20 Have you not seen that God sends down water from the sky, guides it to form springs in the earth, and then, with it, brings forth vegetation of various colours, which later withers, turns yellow before your eyes, and then He makes it crumble away? There is truly a reminder in this for those who possess understanding. 21
