Say: "[Thus speaks God:] 'O you servants of Mine who have attained to faith! Be conscious of your Sustainer! Ultimate good awaits those who persevere in doing good in this world. And [remember:] wide is God's earth, [and,] verily, they who are patient in adversity will be given their reward in full, beyond all reckoning!'" 10 Say: "Verily, I am commanded to serve Allah with sincere devotion; 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: 'I worship Allah and make my religion sincerely His. 14 Worship besides Him whatever you want. The greatest losers are those whose souls and family members will be lost on the Day of Judgment for this is certainly a great loss". 15 They shall have coverings of Fire, above them and covering (of Fire) beneath them; with this Allah does frighten His slaves: "O My slaves, therefore fear Me!" 16 And those who avoid the devils lest they should worship them and turn unto Allah in penitence, for them are glad tidings. Wherefore give thou glad tidings unto 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 Is he then on whom is justified the decree of torment - wilt thou rescue him who is in the Fire? 19 But for those who fear their Lord, are the high chambers with more high chambers built above them – rivers flowing beneath them; a promise of Allah; Allah does not renege on 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
