Imam Reza (A.S) declares: Those who want to achieve complete humanity must have three characteristics:
1- Godly characteristic: God doesn’t tell his secrets to anyone and doesn’t reveal people's secrets.
2- Prophets characteristics: Prophets (A.S) lived with people and were among them, but they were never affected by their badness and led them by all their power.
3- Imams' characteristics: Imams (A.S) are patient in disasters and troubles and they seek to be quartered by God.

All Imams (A.S) declare: A perfect man and believer has five signs:
1- Attention to God and fear of him in solitude.
2- To give charity to people when they are poor themselves.
3- To be patient in disasters and troubles.
4- To be tolerant and patient when they are angry, for God's sake.
5- To tell the truth when they fear. When you fear tell the truth. You should always tell the right and the truth.
