Narrated 'Ali bin Abi Talib: that the Messenger of Allah (ﷺ) said: "May Allah have mercy upon Abu Bakr, he married me to his daughter, and he carried me to the land of Hijrah, and he freed Bilal with his wealth. May Allah have mercy upon 'Umar, he says the truth even if it is sour. The truth caused him to be left without a friend. May Allah have mercy upon 'Uthman, the angels are shy of him. May Allah have mercy upon 'Ali. O Allah! Place the truth with him wherever he turns."
