The God says in Surah Faathir verse 43: "(Due to) arrogance in the earth and plotting of evil; but the evil plot does not encompass except its own people. Then do they await except the way of the former peoples? But you will never find in the way of the God any change, and you will never find in the way of the God any alteration."
The God talks about some of those idolater Quraish Arab noblemen in Meccan period in which a messenger wasn't sent yet to them. They had loudly shouting in front of people, swearing in His Name that if a messenger was sent to them, they would immediately profess their faith to Him through the messenger and becoming the most obedient follower of the teachings transmitted by the messenger more than those earlier nations.
But when Muhammad s.a.w was raised to them and decreed as a prophet and messenger of the God, with His Revelation descends upon him, they refused to accept him and his teaching. They refused to witness his prophethood and arrogantly rejecting the teachings and the Revelation which are His Mercy upon them. It is not enough with them who rejected the messenger, they plotted many evil things and tricks to prevent others from the faith toward Him and His messengers (in which Muhammad s.a.w is their seal).
Their evil plot and doings will only return to them as they were waiting for the Sunnatullah or the way of the God to happen. It was witnessed by previous nations before them where His torments and bad news will descend upon them. Arrogance is also the characteristic of the people who ridiculed others or demonizing them simply because they are Muslims in Europe and elsewhere while most of the people actually never harm them nor doing anything to them. They just read made-up news and listening to things exaggerated by medias and later judging others like they are the God.
As the conclusion, arrogance, showing off, and excessively being proud of oneself are all disgraceful characteristics of creatures and they are evil. The God has grant everyone with the faculty of mind to think on good things and not on evil deeds and plotting evil things for example demonizing others to gain material comfort and praises from medias. This is to all human-being regardless faith, ideologies and beliefs. I also mean this to fellow brothers and sisters (Muslims).
Sealed with prayers for mercy, love, and peace, amin!
