Is anger for one's self more than anger for the religion considered disbelief, or weakness in faith?

Anger for oneself more than anger for Allah is a weakness and deficiency in faith, but it is not disbelief. The perfection of faith makes a person's anger for Allah more intense than their anger for themselves, as is clear from the statement of Aisha, may Allah be pleased with her: "The Messenger of Allah, peace and blessings be upon him, never took revenge for himself for anything done to him, unless the sacred limits of Allah were violated, in which case he would take revenge for Allah."
