Companionship with Bad People
Amir al-Mu'minin 'Ali (as), states: "Shun the companionship of bad people, for a bad friend makes you similar to himself. Unless he succeeds in this respect, he will not accept you as a friend."
'Ali (as) also states: "Avoid the friendship of an evildoer, for he will sell you for a trivial thing."
Associate less with bad people, for you will be distressed; since human nature is apt to acquire habits.
