What are the characteristics of a good leader in Islam?

Reported by Ali r.a, Prophet Muhammad s.a.w. said (in answer to the former’s question about the Prophet’s character assets):

Knowledge is my principal possession

Reason, the root of my religion

Love, my foundation

Longing, my coach

Remembrance of God Almighty, my weapon

Patience, my dress

Contentment, my prize

Poverty, my glory

Abstinence, my calling

Obedience, my measure

Striving (jihad), my character, and

Prayer, my pleasure
