"When we contemplate the duration of the universe, we see it limited to the present moment, which is nothing more but the point which separates two infinities of time. The past and the future are as meaningless as if they did not exist. Is anyone more misguided than the man who barters an eternal future for a moment which passes quicker than the blink of an eye?."
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 HazmWhen you compare yourself with others in matters of wealth, position, and health, you should look at people less favoured than yourself. When you compare yourself with others in matters of religion, knowledge and virtue, look at people who are better than yourself.
Ibn Hazm
