O Thou the Desire of the Divine Messengers! (different prophets and manifestations about the greatness of Baha'u'llah)

Had Muhammad, the Apostle of God, attained this Day, He would have exclaimed: "I have truly recognized Thee, O Thou the Desire of the Divine Messengers!" Had Abraham attained it, He too, falling prostrate upon the ground, and in the utmost lowliness before the Lord thy God, would have cried: "Mine heart is filled with peace, O Thou Lord of all that is in heaven and on earth! I testify that Thou hast unveiled before mine eyes all the glory of Thy power and the full majesty of Thy law! I bear witness, moreover, that through Thy Revelation the hearts of the faithful are well assured and contented." Had Moses Himself attained it, He, likewise, would have raised His voice saying: "All praise be to Thee for having lifted upon me the light of Thy countenance and enrolled me among them that have been privileged to behold Thy face!"

-Summons of the Lord of Hosts by Bahá’u’lláh, Súriy-i-Ra’ís (Tablet to the Chief)

“By the one true God, Elijah hath hastened unto My court and hath circumambulated in the day time and in the night season My throne of glory.” “Solomon in all his majesty circles in adoration around Me in this day, uttering this most exalted word: ‘I have turned my face towards Thy face, O Thou omnipotent Ruler of the world! I am wholly detached from all things pertaining unto me, and yearn for that which Thou dost possess.’”
