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 Surely for those who say, "God is our Lord," and then remain firm, there is no fear or regret. 13 These are the dwellers of the garden, abiding therein: a reward for what they did. 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 they from whom We accept the best of what they have done and pass over their evil deeds, among the dwellers of the garden; the promise of truth which they were promised. 16 But he who says to his parents: "Fie upon you both! Do you hold out the promise to me that I shall be raised up (again) when generations before me have passed away (without rising)?" While they (father and mother) invoke Allah for help (and rebuke their son): "Woe to you! Believe! Verily, the Promise of Allah is true." But he says: "This is nothing but the tales of the ancient." 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 Everyone will have a position proportionate to the degree of his deeds. Finally, God will recompense them for their deeds and they will not be wronged. 19 Upon the day when the unbelievers are exposed to the Fire: 'You dissipated your good things in your present life, and you took your enjoyment in them; therefore today you shall be recompensed with the chastisement of humiliation for that you waxed proud in the earth without right, and for your ungodliness. 20
