- Ibn Hazm
"If you are proud of your descent from virtuous ancestors, how empty their virtue will leave your hands if you yourself are not virtuous. How little pride your ancestors will have in you in this world and the next if you do no good! All men are children of Adam whom Allah created by His own Hands, giving him paradise for a dwelling place and letting His angels bow down before him. But how little is the advantage from this since all the vices dwell in mankind and all the wicked impious people are among their number."
-- Ibn Hazm
