And remember when ye met, He showed them to you as few in your eyes, and He made you appear as contemptible in their eyes: that Allah might accomplish a matter already enacted. For to Allah do all questions go back (for decision).
Yahiya Emerick writes,
‘Abdullah ibn Mas’ud explained that on that day at Badr, the enemy appeared to be smaller in number than it actually was. He said to a man near him that day, “They look about to be ninety in number.” The man replied, “No, they must be about a hundred.” (Ma’ariful Qur’an) In fact they were a thousand!
