Realize O brother eager to aquire knowledge upon whom it is clear in his soul the truthfulness of his desire and excessive thirsting after it if you intend by seeking knowledge competition with others; boastfulness and pride; seeking preference over one’s colleagues; turning the faces of people towards you, or gathering the rubble of this worlds life then you have helped in the destruction of your deen, destroyed your nafs, and bartered your Hereafter for your worldly life.
Thus your bargain has become profitless and your trade has become unproductive. Everything which you have learned will only assist you in your disobedience and it will be a partner with you in your destruction. It is like your selling a sword to a highway robber to rob you with.
