Imam Ali (as) said “Your friends are three and your enemies are three. So, your friends are: your (own) friend, the friend of your friend and the enemy of your enemy. And your enemies are: your (own) enemy, the enemy of your friend and the friend of your enemy.”[i]

Imam Ali (as) said “Make your own self the standard in social conduct between yourself and the other person. Thus do like the same for other person, which you love for your own self. And dislike for others what you dislike and hate for yourself. Do not commit excess upon anyone just as you like it that no one must commit aggression against your own self. And do favor others just as you like others doing favor to you. And what you regard bad for others do regard that bad for yourself as well. If what you like to do with the people is done to you then do love it. (for yourself). And do not say what you do not know, instead even do not say all that you know. And do not utter a word which you dislike other’s saying it to you.”[i]

Imam Ali (as) said “Verily, ordering the good deed and stopping the evil deeds do neither draw the death closer nor diminishes and decreases the sustenance. Instead these increase the reward and turn it into a great one. And the superior of the two is uttering the word of justice before the tyrant and oppressive ruler.”[i]
