As we have seen, Allah will punish those who are arrogant against Him. Rejecting any part of Islam and turning away from it when it applies to you is surely arrogance against Allah. As for whoever competes with me in either of them, I will cast him into the fire without concern. Laa yadkhula al-jannata man kaana fiy qalbihi mithqaala dharratin min kibar. No one will enter Paradise in whose heart there is a single grain of arrogance.
Arrogance is disregard for the truth and contempt for people.
Muslim The cure and the preventive against arrogance is to turn to Allah in humility and submission. If you find any single ruling in Islam which has come to you has not found complete acceptance in your heart, then you have an issue of kibar which must be worked on. The Hour is surely coming without doubt but most of the people do not believe. And your Lord said call to Me that I may respond to you. Verily those who are arrogant before worship of me will enter hell-fire humiliated.
