This book really goes into detail about islams greatest battles and really captures your attention. Only problem i had is the print on the maps of battle scenes which was blurred and too small to read but other than that, i absolutely enjoyed this great piece of history.
Sword of Allah Khalid bin Al-Waleed
This is a great book. I first heard about it from a friend. It was available on the internet, I read a few pages and was hooked. I tried to find a hard copy of the book in a bookshop, but was unsuccessful, until I found it on simplyislam.com. Written by A. I Akram of the Pakistan Army, he dedicated a lot of time to research the book, by visiting the scenes of Khalid's(r.a) battles etc across the Middle East. It is truly inspirational, to read the biography of the Greatest Military General in History. A must read!
