Among His signs is His being manifest, being seen by all, standing as His own proof, and His presence among witnesses in every region, among peoples who fell upon Him even as wolves, and compassed Him about from every side.

Among His signs is His withstanding powerful nations and all-conquering states, and a host of enemies thirsting for His blood, intent at every moment upon His ruin, wheresoever He might be. Verily this is a matter deserving the scrutiny of those who ponder the signs and tokens of God.

Another of His signs is the marvel of His discourse, the eloquence of His utterance, the rapidity with which His Writings were revealed, His words of wisdom, His verses, His epistles, His communes, His unfolding of the Qur’án, both the abstruse verses thereof and the clear. By thy very life! This thing is plain as day to whoever will regard it with the eye of justice.
