This book charts Khalid ibn al-Walid's career as an illustrious and successful warrior, first against the Muslim army, and later as leader of the Muslim army. This change of heart was something even the mighty warrior couldn't resist. For, however great Khalid's struggles on the battlefield, his greatest struggle took place within his own heart. Influenced first by his brother Walid's conversion to Islam, and secondly by his personal encounter with the noble Prophet, peace and blessings be upon him, Khalid could not resist the call of Islam, and became a Muslim.
