Embody the qualities of good etiquette, such as good manners, a cheerful face, spreading the salaam (the salutation), showing forbearance with people, having self-esteem without being haughty, strength which is free from tyranny, and being gallant but not for the sake of zealous partisanship, and being zealous without it being the zealotry of the time of ignorance.
Avoid that which may tarnish your good etiquette, whether it be (in your) nature, speech, or actions. Avoid indulging in degrading actions or evil habits such as conceit, boastfulness, arrogance and being seen in doubtful places. [Shaykh Bakr Aboo Zayd, in ﻣﺨﺘﺼﺮ ﺣﻠﻴﺔ ﻃﺎﻟﺐ ﺍﻟﻌﻠﻢ]
