"..This Siyyid Kazim had already, from his early boyhood, shown signs of remarkable intellectual power and spiritual insight. He was unique among those of his own rank and age. At the age of eleven, he had committed to memory the whole of the Qur'an. At the age of fourteen, he had learned by heart a prodigious number of prayers and recognized traditions of Muhammad. At the age of eighteen, he had composed a commentary on a verse of the Qur'an known as the Ayatu'l-Kursi, which had excited the wonder and the admiration of the most learned of his day. His piety, the gentleness of his character, and his humility were such that all who knew him, whether young or old, were profoundly impressed.
In the year 1231 A.H.,[1] when only twenty-two years old, he, forsaking home, kindred, and friends, departed from Gilan, intent upon attaining the presence of him who had so nobly arisen to announce the approaching dawn of a Divine Revelation. He had been in the company of Shaykh Ahmad for only a few weeks, when the latter, turning to him one day, addressed him in these words: "Remain in your house and cease attending my lectures. Such of my disciples as may feel perplexed will turn henceforth to you, and will seek to obtain from you directly whatsoever assistance they may require. You will, through the knowledge which the Lord your God has bestowed upon you, resolve their problems and tranquillise their hearts. By the power of your utterance you will help to revive the sorely neglected Faith of Muhammad, your illustrious ancestor." These words addressed to Siyyid Kazim excited the resentment and kindled the envy of the prominent disciples of Shaykh Ahmad, among whom figured Mulla Muhammad-i-Mamaqani and Mulla Abdu'l-Khaliq-i-Yazdi. So compelling was the dignity of Siyyid Kazim, however, and so remarkable were the evidences of his knowledge and wisdom, that these disciples were awed and felt compelled to submit."
