Adorn yourself with fine personal behaviour, such as abstinence andforbearance and patience and humbly submitting to the Truth – because the station (of being a student of knowledge) necessitates this, that the student of knowledge has abstinence from that which is in the hands of the people and abstinence from that which is linked to looking at forbidden things.
And forbearance, such that he does not hasten towards punishing if someone treats him badly.
And patience upon the harms which occur by way of that which he hears, whether it be from the common folk or from his peers or from his teacher – so let him be patient and anticipate the reward (from Allaah).
And humbly submitting to the Truth, and likewise showing humility to the creation; he humbly submits to the Truth, meaning that when the Truth is made clear to him, he yields to it and he does not seek anything else to take its place.
And likewise towards the creation; so how many a student has opened doors to his teacher which had not occurred to him;and do not belittle anything…
And it is befitting for the student of knowledge that he stay far away from acting frivolously whether that be in the way he walks or in his dealings with the people – that he is not plentiful in laughing uproariously which (is something) which kills the heart, and removes dignity. Rather he lowers his wing, being one who has the refined manners which are befitting for a student of knowledge.
