Surah Al-Imran, Ayah 134: Those who spend in ease and hardship and those who restrain their anger and pardon people – and Allah (SWT) loves the good-doers.
This is a story about when Ali (R) restrained from anger. The report says that his maid was helping him in his wudu (ablution) when, all of a sudden, the water-pitcher slipped out of her hands spilling water all over Hadrat 'Ali (Zainul'abidin) ibnSayyidna Husain Radhi-AllahuAnh: Allah be pleased with him. His clothes got wet. In was natural that he would be angry. The maid sensed the impending danger and lost no time in reciting the following verse of the Qur'an: (...and those who suppress anger and forgive people). Hearing this, the venerated scion of the Prophet's household lost whatever rash of anger he may have felt. He became totally silent. The maid then recited the second sentence of the verse: (And Allah loves those who do good). Since this sentence implicitly instructs people to be good to others and thus be loved by Allah, so Hadrat 'Ali (Zainul'abidin) ibnSayyidna Husain once he heard it, said: 'All right, go. I give you your freedom.' (Ruh al-Ma'ani with reference to Baihaqi)
