Imam ‘Ali (a.s.) said:
مَنْ رَضِىَ عَنْ نَفْسِهِ كَثُرَ السّاخِطُ عَلَيْهِ
He who is self-conceited will find a lot of people dissatisfied with him.1
Self-love and self-concern in proper measure is necessary for survival, but if it exceeds the bounds, it becomes selfishness and self-conceit.
The self-conceited people never look at their own faults and consider themselves responsible, pure, faultless and important in the society. For this reason they have a lot of unreasonable expectations from people, and this causes widespread anger against them .
