What Is Takabbur?
Keeping aside the common use of a word for different shades of a feeling of pride, it is evil in the feeling which decides that it is wrong and our conscience is the best judge to decide it. In a nutshell, to look down upon people is arrogance (Takkbur) and to feel grateful for having something better than others is a good thing, with the feeling that others might be better in some other respect than us.
