The Sword of Allah Khalid bin Al Walid His Life and Campaigns.
Khalid and the tall boy glared at each other. Slowly they began to move in a circle, the gaze of each fixed intently upon the other, each looking for an opening for his attack and each wary of the tricks that the other might use. There was no hostility in their eyes-just a keen rivalry and an unshakeable determination to win. And Khalid found it necessary to be cautious, for the tall boy was left-handed and thus enjoyed the advantage that all left-handers have over their opponents in a fight. Abu Sulaiman and honorific title Saifullah (Allah’s sword). One of the great companions of Allah’s Prophet (Allah’s blessings and peace be upon him), he embraced Islam between the Treaty of Hudaibiyah and the Conquest of Makkah. He led the Muslim army that defeated the apostates of Arab during the caliphate of the first rightly-guided Caliph, Hazrat Abu Bakr (May Allah be pleased with him!). He led the conquering army that liberated Iraq from the tyranny of the Persians and Syria and Palestine from the oppression of the Romans. He left for Allah’s proximity in 22 AH
