Imam Sajjad (PBUH) said:

Avoid being friend with the following people:

Liars: because they are like mirage, they would make far close and closeness far.

Punk: because he will stab you in the back because of something insignificant.

Stingy: because he will humiliate you in times of need.

Stupid: Because he will harm you instead of benefiting you

The one who cuts his relations with his relatives because he is cursed in three verses
