The Dervish movement died with the Sayyid but the Salihiya order survived and grew.

Evidence

Thus, although his organization perished with his death, the Salihiya brotherhood which had existed outside his movement as well as within it, continued on afterwards and greatly expanded in scope. Nor, probably despite his great gifts of leadership, could he have founded a stable theocratic state. It was difficult enough to create a highly fluid and loosely organized national movement. And what is remarkable is not that this collapsed with his death, but that he ever succeeded in establishing it at all. — I.M. Lewis, I. M. Lewis, A Modern History of the Somali_ Nation…, 239
