Advice of Wahb Ibn Munabbih
Wahb ibn Munabbih (rahimahullah) said:
You should beautify you obedience to Allaah with knowledge, forbearance and understanding. Honor yourself by rejecting the characteristics of the fools instead subject yourself to the characteristics of the scholars. Accustom yourself to the actions of the gentle, patient ones and forbid yourself from the actions of the wretched, make it compulsory upon yourself that you follow the behavior of the scholars and separate yourself from the ways of the wicked people.
