46:16Those are they from whom We accept the best of their deeds, and We overlook their misdeeds, among the dwellers of Paradise—the promise of truth which they are promised.

46:17As for him who says to his parents, “Enough of you! Are you promising me that I will be raised up, when generations have passed away before me?” While they cry for God’s help, “Woe to you! Believe! The promise of God is true!” But he says, “These are nothing but tales of the ancients.”

46:35So be patient, as the messengers with resolve were patient, and do not be hasty regarding them. On the Day when they witness what they are promised, it will seem as if they had lasted only for an hour of a day. A proclamation: Will any be destroyed except the sinful people?
