Forbearance

789. 3. Imam Musa al-Kazim (p): Remain calm and steadfast at the tyranny of your enemies. There can be no better revenge against those who have disobeyed God in dealing with you than to obey God. God will confine them to the chastisement of hell.(B5,C54,T3)

790. 4. Imam Jafar as-Sadiq (p): If you are living in a country governed by your enemies, act with forbearance against their persecutions as a prudent and precautionary measure. This holds good especially for those who are under oppression and act with balanced restraint and caution so that this attitude of yours may earn respect for you. Do not reveal your enmity, otherwise they will overpower you and you will become degraded and despised.(B5,C54,T4)

791. 5. Imam Jafar as-Sadiq (p): One who suppresses his anger, God enhances his eminence in this world and the hereafter. God, the Almighty, the Glorious, said: … those who restrain anger, and forgive people; and God loves those who do good (Q, 3:134), God will bestow on him a high position for (suppressing) his anger.(B5,C54,T5)

792. 6. Imam Jafar as-Sadiq (p): On the Day of Judgement God will fill with His pleasure the heart of the believer who restrains his anger although he is in a position to express it.(B5,C54,T6)
793. 8. Imam Jafar as-Sadiq (p): Behave with restraint with the enemies of the bounties (of God). You cannot take better revenge from those who have disobeyed God in dealing with you than being obedient to God. Verily, God has chosen Islam and approved it. Remain within its limits by being generous and good mannered.(B5,C54,T8)

794. 9. Imam Zainul Abideen (p): One, who chooses the way of God, has to drink two cups. One is to act with restraint in case of anger and the other is to act with patience and steadfastness in a case of adversity.(B5,C54,T9)
795. 13. Imam Jafar as-Sadiq (p): God, the Almighty, the Glorious, likes no one better than a person who restrains his anger either by patience or by forbearance.(B5,C54,T13)
