[3:13] There has already been a sign for you in two hosts that met; one company fighting in the way of God; and another unbelieving; they saw them, twice the like of them; for God confirms with His help whom He will. Surely in that is a lesson for people of vision.
When God wants an affair to be accomplished, He makes many appear few in the eyes of one people and few to appear as many in the eyes of another people. If He covers the insights (baṣīra) of a people, the sharpness of their physical eyes (abṣār) will not benefit them. When He opens the innermost selves of others, the obstructing of their insights (baṣāÌir) will not harm them.
