Arrogance with an Ālim is arrogance towards the Holy Prophet (S)
The Messenger of Allah said:
“Beware! Do not falsify the words of an Ä€lim. Do not reject his statements and do not bear enmity towards him. Be cordial with them, because friendship with the learned is a sign of good morals. And enmity with them is hypocrisy. Beware! Whoever insults an Ä€lim insults me and whoever insults me insults Allah; and whoever insults Allah; his abode is Hell. And (remember), whoever honours an Ä€lim, honours me and whoever honours me honours Allah and whoever honours Allah; his abode shall be Paradise.”
