I could not praise Muhammed with my words; rather, my words were made praiseworthy by Muhammed (SAW).
There are three great and universal things that make known to us our Sustainer. One is the Book of the Universe, another is the Seal of the Prophets (Upon whom be blessings and peace), the supreme sign of the Book of the Universe. Now, we must become acquainted with the Seal of the Prophets {Upon whom be blessings and peace), who is the second and Articulate Proof.
Indeed, look at the collective personality of this proof: the face of the earth has become his mosque, Mecca, his mihrab, and Medina, his pulpit. Our Prophet (SAW}, this clear proof, is leader to all the believers, preacher to all mankind, the chief of all the prophets, lord of all the saints, the leader of a circle for the remembrance of Allah comprising all the prophets and saints. He is a luminous tree whose living roots are all the prophets, and fresh fruits are all the saints; whose claims all the prophets relying on their miracles and all the saints relying on their wonderworking confirm and corroborate. For he declares and claims: There is no god but Allah! And all on left and right, that is, those luminous reciters of Allah’s Names lined up in the past and the future, repeat the same words, and through their consensus in effect declare: “You speak the truth and what you say is right!” What false idea has the power to meddle in a claim that is thus affirmed and corroborated by thousands?
