It is characteristic of love and adoration...
It is characteristic of love and adoration, as opposed to knowledge, science or philosophy, that they have to deal with the heart and as such do not tolerate any rivals. Nothing prevents a scientist or a philosopher who is enslaved to money and wealth from devoting and concentrating his intellectual powers, when necessary, on the study of the problems of philosophy, logic, physics, or mathematics.
But it is not possible, at the same time, that his heart should be full to the brim with love, especially love of a spiritual nature, such as for humanity, or his religion and creed. Certainly, it cannot burn with the light of Divine love nor can it receive an enlightenment or inspiration of a Divine sort.
Consequently, the essential condition for reception of spiritual grace and realization of authentic humanhood is purging the temple of the heart from every trace of materialistic attachments and exterminating from the Ka’bah of the heart all the idols of gold and silver and destroying them.
As we have said before, we should not be led to misinterpret freedom from the bondage of gold and silver, and indifference towards what these metals can be exchanged for, as monastic asceticism which is an attempt to evade responsibility and commitment. Instead, it is only in the light of such zuhd that responsibility and commitment reacquire their real significance and are no longer empty words without content and hollow claims.
The personality of ‘Ali, upon whom be peace, is a glorious example of it. In him zuhd and commitment were combined together. While he was a zahid who had renounced the world, at the same time, he had a heart that was most sensitive to the demands of social responsibility. On the one hand he used to say: What has ‘Ali to do with perishable niceties and short-lived pleasures?
(1) On the other hand, a small injustice or the sight of someone in distress was enough to snatch sleep from his eyes at nights. He was ready to go to bed with an empty stomach lest someone in his dominion might have remained hungry: Shall I stuff my belly with delicious foods while in the Hijaz and Yamamah there may be people who have no hope of getting a loaf of bread or a full meal?(2) There was a direct relation between that zuhd of his and this sensitiveness.
