Khalid bin Al-Waleed (Raz) was the hero of Islam. He led several battles and was always victorious. He conquered the apostates, especially Musailamah Al-Kadhab (the Liar) and restored order and peace to the Arabian Peninsula. He devised military tactics, which, by the help of Allah, made him defeat the huge Roman army. He was very tough with his enemies but at the same time very lenient with his brother Muslims. When he- died, 'Umar bin Al-Khattab (R) cried and said: "Women would never give birth to one-like you."
The Sword of Allah : Khalid bin Al-Waleed (Raz), is written by the late Lieutenant-General A.I. Akram. The author learnt Arabic in order to draw on the earliest historical sources and he visited every one of Khalid's battlefields in order to draw analyses from the viewpoint of military strategy, including reconciling conflicting historians' accounts. Muslim history is replete with great military achievements and glorious Feats of arms. In the annals of war there are no battles that surpass, in brilliance and decisiveness, the battles of Islam; no commanders who surpass, in courage and skill, the gifted generals of Islam. The sword has always held a place of honour in Muslim culture. And yet very little is known in the world today about the military history of lslam.
