'And 'Ali b. al-.Husayn (AS) had a slave girl, who was once pouring water for him when the jug fell and hurt the Imam's face. He raised his head [looking] at her, and the slave girl said [quoting verses from the Qur'an], 'Verily Allah says: And those who suppress their anger. He said, 'I have suppressed my anger.' She said, And excuse the faults of the people. He said, 'I have excused you.' She said, And Allah loves the virtuous. ' He said, 'Go, for you are a free woman for the sake of Allah's pleasure.'
