The unbelievers say, as regards the believers, 'If it had been aught good, they had not outstripped us to it.' And since they are not guided by it, certainly they will say, 'This is an old calumny!' 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 Those are the inhabitants of Paradise, therein dwelling forever, as a recompense for that they have been doing. 14 And We have enjoined upon man, to his parents, good treatment. His mother carried him with hardship and gave birth to him with hardship, and his gestation and weaning [period] is thirty months. [He grows] until, when he reaches maturity and reaches [the age of] forty years, he says, "My Lord, enable me to be grateful for Your favor which You have bestowed upon me and upon my parents and to work righteousness of which You will approve and make righteous for me my offspring. Indeed, I have repented to You, and indeed, I am of the Muslims." 15 These are the ones whose good deeds We will accept, and overlook their shortfalls – among the People of Paradise; a true promise which is being given to them. 16 But he who says to his parents: “Fie on you! Do you threaten me that I shall be resurrected, although myriad generations have passed away before me (and not one of them was resurrected)?” The parents beseech Allah (and say to their child): “Woe to you, have faith. Surely Allah's promise is true.” But he says: “All this is nothing but fables of olden times.” 17 Such are they against whom the statement is realized concerning the nations of humans and jinn alike that passed away before them; they were the losers. 18 And for all there will be ranks from what they do, that He may pay them for their deeds; and they will not be wronged. 19 On the day when the disbelievers will be exposed to the fire, they will be told, "You have spent your happy days during your worldly life and enjoyed them. On this day you will suffer a humiliating torment for your unreasonably arrogant manners on earth and for the evil deeds which you have committed". 20
