Pride (Kibr) is the off-shoot of Ujb. When a person perceives a merit in himself and is overcome by a sense of pleasure, exultation and vanity, that state is called Ujb. Pride is the name of a psychic state in which a person feels a sense of superiority and behaves highhandedly with others.

The sense of pride or “Takabbur” may be for good attributes or even sinful behavior; for true faith or invalid faith, good qualities or praiseworthy attributes, righteous or sinful deeds. 

Some of the Ayahs of the Glorious Qur'an are given below:

Surah al-Baqarah Ayah 34, “When We told the angels to prostrate before Adam, they all obeyed except Iblis, who abstained out of arrogance, and so he became one of those who deny the truth.” Surah al-A'raf Ayah 13, “The Lord ordered Shaytan to get out of the garden saying, “This is no place for you to be proud. Get out of this place, for you are worthless.”

Surah-al-Nahl Ayah23, “Allah certainly knows whatever you conceal or reveal. He does not love the proud ones.” Surah al-A'raf Ayah 146, “We will deprive those who are wrongly proud in the land of the blessing of revelations.” Surah Luqman Ayah 18,, “Do not show people that you are an inferior person. Do not walk around puffed-up with pride.” Surah al-Gha'fir Ayah 35 and Ayah 76,

“Thus Allah cause to go astray the skeptical , transgressing people, those who dispute the revelations of Allah without having received clear authority. This act greatly angers Allah and the believers. Thus Allah seals the hearts of every arrogant oppressor.” “Enter the gates of Hell to live there in forever How terrible is the dwelling of the arrogant ones.” Surah al-Nisa Ayah 36, “Worship Allah and consider no one equal to Him. Be kind to your parents, relatives, orphans, the destitute, your near and distant neighbors, your companions, wayfarers, and your slaves.

Allah does not love the proud and boastful ones.” Surah al-Ah'qaf Ayah 20, “On this day you will suffer a humiliating torment for your unreasonably arrogant manners on earth and for the evil deeds which you have committed.” Surah al-Zumar Ayah 60, “On the Day of Judgment you will see the faces of those who had invented falsehood against Allah blackened. Is not Hell the dwelling of the arrogant ones.” 

The Infallible imam Ja'far as-Sadiq (a.s.) said, “There is no person who does not have a harness on his head, and an angel who attends to it. Whenever he is proud, the angel says, 'Be humble, lest God should disgrace you. Thus he is the greatest of human beings in his own eyes, whereas in other people's eyes he is the smallest of creatures. When he is humble and modest, God removes the harness from his head and the angel says to him, 'Elevate yourself, as God Almighty is elevating you'. Thus he is the smallest of persons in his own eyes, while the most elevated and exalted in the eyes of others.” (Al-Kafi volume 3 page 424)

He (a.s.) further said, “Refrain from pride and self-glorification, since pride is God Almighty's mantle, and one who contests with God regarding His cloak, God will shatter him and disgrace him on the Day of Resurrection.”
