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 HazmDo not use your energy except for a cause more noble than yourself. Such a cause cannot be found except in Almighty God Himself: to preach the truth, to defend womanhood, to repel humiliation which your Creator has not imposed upon you, to help the oppressed. Anyone who uses his energy for the sake of the vanities of the world is like someone who exchanges gemstones for gravel. There is no nobility in anyone who lacks faith. The wise man knows that the only fitting price for his soul is a place in Paradise.
Ibn Hazm
