Indeed, those who dispute concerning the signs of Allah without [any] authority having come to them – there is not within their breasts except pride, [the extent of] which they cannot reach. So seek refuge in Allah. Indeed, it is He who is the Hearing, the Seeing. (Quran Surah Ghafir: 56)
Arrogant people like to talk more and do less, whereas the people who are sincere like to do more and talk far less. Everyone has to deal with pride on some level, and you have to constantly seek refuge in Allah (swt) from this. Arrogance and pride are some of the most difficult things for people to overcome; it sneaks up on you without you even realizing. Knowledge can be your path to pride and arrogance. Look at iblees, who was a leader of angels and one of the most knowledgeable. ‘Ilm alone will not save you. You need to seek and take refuge in Allah (swt) from pride and arrogance. No matter what level you are at, we are all susceptible to it.
