Meditate, O Shaykh, and be fair in what thou sayest. The followers of Shaykh-i-Ahsá’í (Shaykh Aḥmad) have, by the aid of God, apprehended that which was veiled from the comprehension of others, and of which they remained deprived. Briefly, in every age and century differences have arisen in the days of the manifestation of the Daysprings of Revelation, and the Dawning-Places of inspiration, and the Repositories of Divine knowledge, differences which have been caused and provoked by lying and impious souls. To expatiate on this is not permissible. Thou art thyself better acquainted and more familiar with the idle fancies of the superstitious and the vain imaginings of the doubters.
