Shaykh Sultán was also among those who fell under the spell of Táhirih. On his return from Shíráz, he identified himself with the Faith, boldly and assiduously promoted its interests, and did his utmost to execute her instructions and wishes. Another admirer was Shaykh Muḥammad-i-Shibl, the father of Muḥammad-Mustafá, an Arab native of Baghdád who ranked high among the ‘ulamás of that city. By the aid of this chosen band of staunch and able supporters, Táhirih was able to fire the imagination and to enlist the allegiance of a considerable number of the Persian and Arab inhabitants of ‘Iráq, most of whom were led by her to join forces with those of their brethren in Persia who were soon to be called upon to shape by their deeds the destiny, and to seal with their life-blood the triumph, of the Cause of God.
