Say: O my servants who believe! be careful of (your duty to) your Lord; for those who do good in this world is good, and Allah's earth is spacious; only the patient will be paid back their reward in full without measure. 10 Say (O Muhammad): Lo! I am commanded to worship Allah, making religion pure for Him (only). 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 thou: it is Allah I worship, making for Him my religion exclusive 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 are mountains of fire and beneath them are mountains of fire; Allah scares His bondmen with this; “O My bondmen! Fear Me!” 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 who listen [closely] to all that is said, and follow the best of it: [for] it is they whom God has graced with His guidance, and it is they who are [truly] endowed with insight! 18 So will the one upon whom the Word of punishment has proved true, ever be equal to those who are forgiven? So will you guide and save the one who deserves the fire? (Because the hearts of some disbelievers are sealed). 19 But those who fear their Lord shall have lofty mansions built over one another beneath which rivers flow. This is Allah's promise and never does Allah fail to fulfil His promise. 20 Seest thou not that Allah sends down rain from the sky, and leads it through springs in the earth? Then He causes to grow, therewith, produce of various colours: then it withers; thou wilt see it grow yellow; then He makes it dry up and crumble away. Truly, in this, is a Message of remembrance to men of understanding. 21
