The second affair with relation to Islam that is related to Khalid, and which shows the nature of Khalid, is that during the occupation of Yemen, when Ali (a.s.) learnt that those tribes who had embraced Islam around Yemen, had renegaded and were preparing to fight, he went with his army to confront them. These apostates, influenced by the good nature and disposition of Ali (a.s.) again entered the fold of Islam.
There is no doubt that the bravery of manners of Ali (a.s.) had been instrumental in this, but Khalid did not give up his natural evil deeds. He had an old enmity with Ali (a.s.). Khalid consulted Buraidah Al-Haseeb and wrote a letter to the Messenger of Allah (S) complaining about Ali (a.s.). The Prophet was very angry on getting this letter and told Buraidah: “Have you become a hypocrite? Ali (a.s.) is from me and is superior to you and your people.
Whatever he commands is according to the command of Allah. Seek refuge from Allah. Otherwise, the enemy of Ali is my enemy, and my enemy is the enemy of Allah.” Hearing this, Buraidah was frightened and he said: “I wish, I were buried before complaining about Ali al-Murtadha’ (a.s.).” After that he never opposed Ali (a.s.); but the enmity of Khalid remained as it was. On the basis of this enmity, Ahlul Sunnah call Khalid, ‘His Eminence, Khalid’.
If such people are called His Eminence, then what should be title of those companions of the Holy Prophet (S) who really possessed those praiseworthy qualities? The fact is that it is due to their opposition to Ali (a.s.) that people like Khalid Ibn Walid, Talha, Zubair and Muawiyah are called ‘His Eminence’. In addition to this, Ahlul Sunnat have given Khalid the title of ‘Sword of Allah’ (Saifullah). Only Ahlul Sunnat know how Khalid began to be called by the title of Saifullah.
We have already explained in the foregoing pages that this title is exclusively for Ali (a.s.) and indeed no one else deserves to be called thus, because doubtlessly, he was the sword of Allah. His sword, Zulfiqar, was a sign of his being the ‘Sword of Allah’. From which principle, which rule, which verse and which prophecy can Khalid have the right to the title of ‘Sword of Allah’? It is beyond the scope of investigation. Bravery, and not ferocity is required if one has to be ‘Sword of Allah’.
Another example of his animal behavior is presented below; which shows his heartlessness, cruelty and selfishness etc.
