And the disbelievers said regarding the Muslims, “If there were any good in it, the Muslims would not have surpassed us in achieving it!” and since they did not receive guidance with it, they will now say, “This is an old slander.” 11 Yet before it there was the Book of Moses which was an authority, and a mercy. This (Koran) is the Book confirming it (the other untampered Books) in theArabic tongue, to warn the harmdoers and to give glad tidings to those who do good. 12 Those who have said, "Our Lord is God," and are steadfast in their belief need have no fear or be grieved. 13 Such are rightful owners of the Garden, immortal therein, as a reward for what they used to do. 14 And We have enjoined on man doing of good to his parents; with trouble did his mother bear him and with trouble did she bring him forth; and the bearing of him and the weaning of him was thirty months; until when he attains his maturity and reaches forty years, he says: My Lord! grant me that I may give thanks for Thy favor which Thou hast bestowed on me and on my parents, and that I may do good which pleases Thee and do good to me in respect of my offspring; surely I turn to Thee, and surely I am of those who submit. 15 Those are they from whom We accept the best of what they do, and overlook their evil deeds. (They are) among the owners of the Garden. This is the true promise which they were promised (in the world). 16 And he who saith unto his parents: fie upon you both! threaten me ye that I shall be taken forth, whereas generations have passed away before me? and the twain implore Allah's assistance; woe unto thee! come to believe! verily the promise of Allah is true; yet he saith: naught is this but fables of the ancients. 17 Such are those on whom the Word concerning nations of the jinn and mankind which have passed away before them hath effect. Lo! they are the losers. 18 And for all persons are ranks according to their deeds; and so that He may repay them in full for their deeds, and they will not be wronged. 19 And on the Day when the unbelievers will be exposed to the Fire, they will be told: “You have exhausted your share of the bounties in the life of the world, and you took your fill of enjoyments. So, degrading chastisement shall be yours on this Day for you waxed arrogant in the earth without justification and acted iniquitously.” 20
