CONCEIT

If anyone has the complex of self-importance or struts on wearing good clothes etc,is an evil and vice even if he does not look down upon others.The Tradition says:”This habits disrupts Iman(Faith).Such person does not care to correct himself,because of self conceit,he never looks to his own defects”
Its remedy is that one should recall and scrutinize one's defects and shortcomings and judge his actions and habits and understand that any good in him has been given by Allah and it is not his own achievement and should be thankful to Allah and pray that he may not be deprived of whatever virtues he has.
