Imam Sadiq (a.s) said: “I advise you to fear God and tell the truth, to acquire piety and to strive to worship God, and to abandon sins. Beware that whoever does not control his wrath does not belong to our nation. So is one who does not honor friendship and is not a good friend, does not associate well, disturbs his neighbors, hurts his companions, does not treat his friends well, and does not oppose the one who tries to misguide him. I advise you to piety, abstention, concealing of faith and hiding your secrets. I swear by God that when I looked to the right and to the left, I saw people each going on their own way. I chose the right path from among all that dirt and dust. You should also fear God while you have time since there is no power other than God's Power.”
