Shoghi Effendi writes in " God Passes By", p. 26: "The Báb was still in Máh-Kú when He wrote the most detailed and illuminating of His Tablets to Muḥammad Sháh. Prefaced by a laudatory reference to the unity of God, to His Apostles and to the twelve Imáms; unequivocal in its assertion of the divinity of its Author and of the supernatural powers with which His Revelation had been invested; precise in the verses and traditions it cites in confirmation of so audacious a claim; severe in its condemnation of some of the officials and representatives of the Sháh’s administration, particularly of the “wicked and accursed” Ḥusayn Khán; moving in its description of the humiliation and hardships to which its writer had been subjected, this historic document resembles, in many of its features, the Lawḥ-i-Sulṭán, the Tablet addressed, under similar circumstances, from the prison-fortress of ‘Akká by Bahá’u’lláh to Náṣiri’d-Dín Sháh, and constituting His lengthiest epistle to any single sovereign."
