If all you take away from this talk, is what I say next, it's enough.
Imam Malik Said: "I knew a people who had no faults and they preoccupied their selves with the faults of others, and God gave them faults.
I knew another people who had faults and they preoccupied themselves with purifying their faults and ignored the faults of others; and God removed their faults."
Shaikh Hamza Yusuf
( Islamic Theology 2013 )
