Say to My believing servants, "Have fear of your Lord. Those who act righteously in this life will receive good reward. The land of God is vast. God will recompense the deeds of those who have exercised patience, without keeping an account". 10 Say: I am commanded that I should serve Allah, being sincere to Him in obedience. 11 "And I am commanded (this) in order that I may be the first of those who submit themselves to Allah (in Islam) as Muslims." 12 Say, "I fear, if I disobey my Lord, the punishment of a Terrible Day." 13 Say: Allah (it is Whom) I serve, being sincere to Him in my obedience: 14 So worship what you like besides Him. Say (O Muhammad SAW): "The losers are those who will lose themselves and their families on the Day of Resurrection. Verily, that will be a manifest 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 Those who eschew Evil,- and fall not into its worship,- and turn to Allah (in repentance),- for them is Good News: so announce the Good News 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 (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 As against this they who of their Sustainer are conscious shall [in the life to come] have mansions raised upon mansions high, beneath which running waters flow: [this is] God's promise - [and] never does God fail to fulfill His promise. 20 Do you not see that Allah sends down rain from the sky and makes it flow as springs [and rivers] in the earth; then He produces thereby crops of varying colors; then they dry and you see them turned yellow; then He makes them [scattered] debris. Indeed in that is a reminder for those of understanding. 21
