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, [O Muhammad], "Indeed, I have been commanded to worship Allah, [being] sincere to Him in religion. 11 and I am bidden to be foremost among those who surrender themselves unto God." 12 Say: 'Truly I fear, if I should rebel against my Lord, the chastisement of a dreadful day.' 13 Say: 'God I serve, making my religion His sincerely; 14 and [it is up to you, O sinners, to] worship whatever you please instead of Him!" Say: "Behold, the [true] losers will be they who shall have lost their own selves and their kith and kin on Resurrection Day: for is not this, this, the [most] obvious loss? 15 Above them will be a covering of fire, below them a cloud (of flames). With this does God warn His creatures: "O My creatures, fear Me." 16 Those who shun the worship of idols and turn in repentance to Allah for them glad tidings. Therefore give good tidings to My worshipers, 17 who give ear to the Word and follow the fairest of it. Those are they whom God has guided; those -- they are men possessed of minds. 18 On the other hand, could one on whom [God's] sentence of suffering has been passed [be rescued by man]? Couldst thou, perchance, save one who is [already, as it were,] in the fire? 19 But those who have feared their Lord - for them are chambers, above them chambers built high, beneath which rivers flow. [This is] the promise of Allah. Allah does not fail in [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
