Narrated to him by Ibn `Abbas (RA) who said: While on that day a Muslim was chasing a disbeliever who was going ahead of him, he heard over him the swishing of the whip and the voice of the rider saying: Go ahead, Haizum! [1] He glanced at the polytheist who had (now) fallen down on his back. When he looked at him (carefully he found that) there was a scar on his nose and his face was torn as if it had been lashed with a whip, and had turned green with its poison. An Ansari came to the Messenger of Allah (ﷺ) and related this (event) to him. He said: You have told the truth. This was the help from the third heaven. The Muslims that day (i.e. the day of the Battle of Badr) killed seventy persons and captured seventy. [2]
