Sahaba

One of the fundamental war techniques of Khalid bin Walid (radiallahu ‘anh) is that he never wasted time. He might make mistakes from it, but he moved the entire army at the speed of a single rider. Most armies crawl at a slow pace, but his army moved quickly. The Muslims were all very well disciplined. If you were in his army, you moved fast. He moved so quickly that after one battle took place at one village, before the defenders regrouped, he arrived at the next village and attacked.
