سورة Al-Imran ( The Famiy of Imran ) - الآية 13

Of a surety there hath been unto you a sign, the two hosts that met, one host fighting in the way of Allah, and the other disbelieving, beholding themselves, with their own eyes, twice as many as they. And Allah aideth with His succour whomsoever He will. Verily herein is a lesson for men of insight.
