of His singleness, and the Embodiments of His sanctity, and failed to believe in them and submit to their authority. The reason was that they did not see the sun darken, or the stars of heaven fall to the ground, or the angels visibly descend upon the earth, and hence they contended with the Prophets and Messengers of God. Nay, inasmuch as they found them at variance with their own faith and creed, they hurled against them such accusations of imposture, folly, waywardness, and misbelief as I am ashamed to recount. Refer to the Qur’án, that thou mayest find mention of all this and be of them that understand its meaning. Even to this day do these people await the appearance of that which they have learned from their doctors and imbibed from their divines. Thus do they say: “When shall these signs be made manifest, that we may believe?” But if this be the case, how could ye refute their arguments, invalidate their proofs, and challenge them concerning their faith and their understanding of their Books and the sayings of their leaders?
