"Verily, He Who was hidden in the knowledge of God and is mentioned in the Holy Scriptures hath appeared."

"Say, by the righteousness of God! The All-Merciful is come invested with power and sovereignty. Through His power the foundations of religions have quaked and the Nightingale of Utterance hath warbled its melody upon the highest branch of true understanding. Verily, He Who was hidden in the knowledge of God and is mentioned in the Holy Scriptures hath appeared. Say, this is the Day when the Speaker on Sinai hath mounted the throne of Revelation and the people have stood before the Lord of the worlds. This is the Day wherein the earth hath told out her tidings and hath laid bare her treasures; when the oceans have brought forth their pearls and the divine Lote-Tree its fruit; when the Sun hath shed its radiance and the Moons have diffused their lights, and the Heavens have revealed their stars, and the Hour its signs, and the Resurrection its dreadful majesty; when the pens have unloosed their outpourings and the spirits have laid bare their mysteries. Blessed is the man who recognizeth Him and attaineth His presence, and woe betide such as deny Him and turn aside from Him. I beseech God to aid His servants to return unto Him. Verily He is the Pardoner, the Forgiving, the Merciful."
