SHAFAQNA – It is narrated from Imam Baqer (AS) who said: The three destructive characteristics which break the back of the human being are: The person who considers his/her deeds to be big and significant; the person who forgets his/her own sins; and the person who is self-centred (egocentric, self-obsessed), and acts (only) according to his/her own opinion [1].
