‘Abdu’l-Bahá tells us: Be silent concerning faults

'Abdu'l-Bahá tells us:
To be silent concerning the faults of others, to pray for them, and to help them, through kindness, to correct their faults.

To look always at the good and not at the bad. If a man has ten good qualities and one bad one, to look at the ten and forget the one; and if a man has ten bad qualities and one good one, to look at the one and forget the ten.
