SHAFAQNA – Do not count any one inferior and do not insult others. If a person is older than you say, he/she is better than me because he/she is older than me and has done more prayers than me. If a person is younger than you say, he/she is better than me because he/she has committed less sins then me. If a person is the same age as you say, I am aware of my sins and not aware of his/her sins. Therefore be considerate and respect all people .
 Translated from Tariqe Wasl by Mojtahedi Tehrani, Page 128.
