Arrogance, the mother of all evils

Arrogance is one of the characteristics of Iblees, so whoever wants to be arrogant should realize that he is acquiring a characteristic of the devils, and that he is not acquiring a characteristic of the noble angels who obeyed their Lord and fell down prostrate. Moreover, arrogance may be the cause of a person being deprived of Paradise and may mean that the Lord of Glory will not even look at him, as it says in the following two ahaadeeth:

It was narrated from 'Abd-Allaah ibn Mas'ood that the Prophet (peace and blessings of Allaah be upon him) said: "No one who has an atom's-weight of arrogance in his heart will enter Paradise." A man said, "O Messenger of Allaah, what if a man likes his clothes and his shoes to look good?" He said, "Allaah is Beautiful and loves beauty. Arrogance means rejecting the truth and looking down on people."
