Arrogance is a fire that destroys one's deeds and it has been mentioned in the narrations that you must consider yourself lower than the one who is older than you, assuming that they might have said one Allāhu akbar (الله أكبر),"God is [the] greatest" more than you, and you must consider the one who is younger than you being in higher spiritual level, assuming they might have committed less sins than you
