A certain Muhammad Karím, a native of Shíráz, who had been a witness to the rapidity and the manner in which the Báb had penned the verses with which He was inspired, has left the following testimony to posterity, after attaining, during those days [in Baghdad], the presence of Bahá’u’lláh, and beholding with his own eyes what he himself had considered to be the only proof of the mission of the Promised One: “I bear witness that the verses revealed by Bahá’u’lláh were superior, in the rapidity with which they were penned, in the ease with which they flowed, in their lucidity, their profundity and sweetness to those which I, myself saw pour from the pen of the Báb when in His presence. Had Bahá’u’lláh no other claim to greatness, this were sufficient, in the eyes of the world and its people, that He produced such verses as have streamed this day from His pen.”
