Tell them (O Prophet): “O you servants of Mine who believe, have fear of your Lord. A good end awaits those who did good in this world. Allah's earth is spacious. Verily those who persevere shall be granted their reward beyond all reckoning.” 10 Say (O Muhammad SAW): "Verily, I am commanded to worship Allah (Alone) by obeying Him and doing religious deeds sincerely for Allah's sake only and not to show off, and not to set up rivals with Him in worship; 11 And I am commanded that I shall be the first of those who submit. 12 Say, "I fear, if I disobey my Lord, the punishment of a Terrible 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 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 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 And those who avoid the devils lest they should worship them and turn unto Allah in penitence, for them are glad tidings. Wherefore give thou glad tidings unto My bondmen, 17 who listen to what is said and follow what is best in it. These are the ones God has guided; these are the people endowed with understanding. 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 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 Do you not see that God sends down water from the sky, then makes it flow in rills on the earth, and brings forth corn from it which, having passed through changes of shade and colour, comes to ripen, and you see it autumnal yellow; then He reduces it to chaff. There are indeed lessons in this for those who are wise. 21
