Mu'aadh ibn Jabal,
(radi' Allaahu 'anhu)
said:
"Knowledge is a comforting friend in times of loneliness,
it is the best companion during travels,
and it is the inner friend who speaks to you in your privacy.
Knowledge is the discerning proof of what is right and what is wrong,
and it is the positive force that will help you surmount the trials of comfort, as well as those of hardships.
Knowledge is your most powerful sword against your enemy,
and finally,
it is your most dignifying raiment in the company of your close companions."
