Imam Sajjad (a.s) had a maid who was pouring water over his hands once. The water jar fell down and the Imam's hand got injured. When the Imam looked up at her, she said: “God the Almighty said: “Who restrain anger...” [The Holy Quran: Ali-i- Imran 3:134] The Imam (a.s) said: “I restrained my anger.” She continued the same verse: “....and pardon (all) men.” [The Holy Quran: Ali-i-Imran 3:134] The Imam (a.s) said: “I pardon you”, but she continued the same verse: “...for God loves those who do good.” [The Holy Quran: Ali-i-Imran 3:134] Then Imam Sajjad (a.s) said: “Go, you are freed for the sake of God.”
