The one who acts without knowledge is like a wayfarer without a way, and such a person ruins more than he fixes. Therefore seek knowledge, in a way that doesn't harm your worship, and seek worship, in a way that doesn't harm your knowledge seeking, for there was a nation that sought worship and neglected knowledge, until they went out with their swords against the ummah (nation) of Muhammad peace be upon him. Had they sought knowledge, it wouldn't have led them to what they did.
