Those who deny the truth say of the believers, "If there were any good in this Quran, they would not have believed in it before we did." And since they refuse to be guided by it, they say, "This is an ancient fabrication." 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 Surely for those who say, "God is our Lord," and then remain firm, there is no fear or regret. 13 They are the people of Paradise. They shall remain in it forever as a reward for their deeds. 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 We accept from such people the best of what they do and We overlook their bad deeds. They will be among the people of Paradise -- this is a true promise that has been given to them. 16 And whoso saith unto his parents: Fie upon you both! Do ye threaten me that I shall be brought forth (again) when generations before me have passed away? And they twain cry unto Allah for help (and say): Woe unto thee! Believe! Lo! the promise of Allah is true. But he saith: This is naught save fables of the men of old: 17 Those are the ones upon whom the word has come into effect, [who will be] among nations which had passed on before them of jinn and men. Indeed, they [all] were losers. 18 And for each are ranks according to that which they have worked, that He may repay them in full for their works; and they shall not be wronged. 19 And on the day when those who disbelieve shall be brought before the fire: You did away with your good things in your life of the world and you enjoyed them for a while, so today you shall be rewarded with the punishment of abasement because you were unjustly proud in the land and because you transgressed. 20
