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: 'I have been commanded to serve God making my religion His sincerely; 11 "And I am commanded to be the first of those who bow to Allah in Islam." 12 Say: I fear, if I disobey my Lord, the chastisement of a grievous 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 Serve then what you like besides Him. Say: The losers surely are those who shall have lost themselves and their families on the day of resurrection; now surely that is the clear 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 eschew the serving of idols and turn penitent to God, for them is good tidings! So give thou good tidings to My servants 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 for those who truly feared their Lord, there will be tall mansions, built up storey upon storey, beneath which there will be rivers flowing. This is God's promise: God never fails in His promise. 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
