Being proud (Mutkabbir) tantamount to grandstanding. Such behavior means; one is worse than the dumbest animal, who would simply behave naturally instinctually. How come, a rational being could willfully fall for such a low level, let alone a believer?
“Turn not thy cheek in scorn toward people, nor walk with pertness on the earth. Verily, God loveth not any braggart boaster” (Q,31:18)
“Surely the vilest of the animals, in the sight of Allah, are the deaf, the dumb, who do not use reason” (Q,8:22)
“They have hearts wherewith they understand not; they have eyes wherewith they see not, and they have ears wherewith they hear not. These are as the cattle nay, but they are worse! These are neglectful”. (Q,7:179)
Hadith:
Pride is (only) Allah’s mantle!
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.
