Angered by the Hatt-i Hümayun, a group of Muslim theologians and students plotted a conspiracy against the Sultan and his ministers, but they were arrested in 1859. Under interrogation their leaders claimed that the Hatt-i Hümayun was a contravention of shariah law because it had granted Christians equal rights to Muslims. Sheikh Ahmet, one of the main conspirators, claimed that the Christians had obtained these rights only through the help of foreign powers, and that the concessions would mean the end of the privileged position of Islam in the Ottoman Empire.
