Since Khalid bin Walid was a deadly enemy of Imam Ali (a.
Since Khalid bin Walid was a deadly enemy of Imam Ali (a.s.) he sent Buraidah Aslami to the Messenger of Allah (S) with the complaint that Imam Ali (a.s.) has misappropriated booty and taken from Khums a maid for himself, and to say whatever else against Ali (a.s.). When Buraidah Aslami came to the Holy Prophet (S), Umar was present there who asked about the outcome of the battle and the purpose of his visit.
He was told that he had come to complain about Ali (a.s.) and mentioned the matter related to the slave girl. Umar was elated at this and he ushered Buraidah inside so that the Holy Prophet (S) is sure to be angry with Ali (a.s.) since he was married to the Prophet’s daughter. Buraidah entered into the Prophet and delivered Khalid’s letter. The Prophet opened the letter and it was read out to him.
As he noted the account of the ‘misappropriation’ of Imam Ali (a.s.), his fury intensified and his complexion altered. Then Buraidah said: O Messenger of Allah (S), if people are allowed such discretion in booty, the share of Muslims would be destroyed. The Holy Prophet (S) said: Woe be on you, O Buraidah, have you become a hypocrite. You should remember that Ali is entitled to all that from booty as I am entitled.
Ali Ibn Abi Talib (a.s.) is best for you from all the people and is better than all the people of my Ummah after me. O Buraidah keep away from Ali’s enmity. If you have enmity with him, the Almighty Allah will have enmity with you. Buraidah says that at time he was so embarrassed that he wished the earth would swallow him. He said: I seek refuge from the fury of Allah and from the fury of the Messenger of Allah (S). O Messenger of Allah (S) seek forgiveness on my behalf from the Almighty Allah.
After this I would never harbor enmity to Ali (a.s.) and will not say anything except good with regard to him. So the Holy Prophet (S) prayed for his forgiveness and his sin was forgiven. Part Two: Deputation of Amirul Momineen (a.s.) to Yemen Shaykh Mufeed and Shaykh Tabarsi have narrated that the Messenger of Allah (S) now sent Khalid bin Walid to the people of Yemen in order to invite them to Islam; and a group of Muslims also accompanied him, in which Baraa bin Azib was also included.
In spite of staying there for six months they could not convert a single person there.
