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 Those who have said, "Our Lord is God," and are steadfast in their belief need have no fear or be grieved. 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 It is [such as] these from whom We shall accept the best that they ever did, and whose bad deeds We shall overlook: [they will find themselves] among those who are destined for paradise, in fulfillment of the true promise which they were given [in this world]. 16 But (there is one) who says to his parents, "Fie on you! Do ye hold out the promise to me that I shall be raised up, even though generations have passed before me (without rising again)?" And they two seek Allah's aid, (and rebuke the son): "Woe to thee! Have faith! for the promise of Allah is true." But he says, "This is nothing but tales of the ancients!" 17 It is [such as] these upon whom the sentence [of doom] will fall due, together with the [other sinful] communities of invisible beings and humans that have passed away before their time. Verily, they will be lost: 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 those who disbelieve are exposed to the Fire (it will be said): Ye squandered your good things in the life of the world and sought comfort therein. Now this day ye are rewarded with the doom of ignominy because ye were disdainful in the land without a right, and because ye used to transgress. 20
