Likewise, ere the beauty of Muhammad was unveiled, the signs of the visible heaven were made manifest. As to the signs of the invisible heaven, there appeared four men who successively announced unto the people the joyful tidings of the rise of that divine Luminary. Ruz-bih, later named &Salman, was honoured by being in their service. As the end of one of these approached, he would send Ruz-bih unto the other, until the fourth who, feeling his death to be nigh, addressed Ruz-bih saying: "O Ruz-bih! when thou hast taken up my body and buried it, go to Hijaz for there the Day-star of Muhammad will arise. Happy art thou, for thou shalt behold His face!"

And now concerning this wondrous and most exalted Cause. Know thou verily that many an astronomer hath announced the appearance of its star in the visible heaven. Likewise, there appeared on earth Ahmad and Kazim, (2) those twin resplendent lights--may God sanctify their resting-place!
