Say (O Muhammad SAW): "O My slaves who believe (in the Oneness of Allah Islamic Monotheism), be afraid of your Lord (Allah) and keep your duty to Him. Good is (the reward) for those who do good in this world, and Allah's earth is spacious (so if you cannot worship Allah at a place, then go to another)! Only those who are patient shall receive their rewards in full, without reckoning." 10 Say, "I am commanded to worship God and be devoted to His religion 11 And I am commanded to be the first of those who submit." 12 Say, "I am afraid that for disobeying my Lord I shall suffer the torment of the great day". 13 Say: "I worship God with devotion all-exclusive for Him. 14 so serve what you will apart from Him.' Say: 'Surely the losers are they who lose themselves and their families on the Day of Resurrection; is not that the manifest loss? 15 There shall be sheets of fire above them and beneath them. This is the end against which Allah warns His servants. So dread My wrath, O you servants of Mine!” 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 He against whom the word of chastisement is realized -- shalt thou deliver him out of the Fire? 19 But those who fear their Lord, for them are lofty chambers with lofty chambers above them, built whereunder rivers flow: the promise of Allah, and Allah faileth not the appointment. 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
