Arguing

'Arguing with people removes the blessings of knowledge from one's heart' ~ Imam Malik.

Taqwa

When Ibn `Aun was bidding farewell to another man, he said:

“Upon you is to fear Allah, for the one who has taqwaa never feels loneliness”.

The Intelligent Person

 “The intelligent person is not one who merely knows what is good
and what is bad. The intelligent person is one who, when he sees what
is good, follows it, and when he sees evil, shuns it.” -  Sufyân b. ‘Uyainah
