أحمد بن زين الدين الأحسائي
Before the death of Shaykh Ahmad, he appointed Siyyid Kázim of Rasht to lead the Shaykhí movement, which he did until his death in 1843. Siyyid Kázim formulated many of the thoughts that were ambiguously expressed by Shaykh Ahmad including the doctrine of salvation history and the cycles of revelation. His teaching brought a sense of millenarian hope among the Shaykhis that the Hidden Imam may return. Siyyid Kazim did not leave a successor, but before his death in December, 1843, he had counselled his followers to leave their homes to seek the Mahdi, who according to his prophecies would soon appear.
