Though tolerant in religion, Talal was careful to avoid the suspicion of lukewarmness towards the Wahhabi formulas.
The Wahhabi leader was soon after sent to Constantinople, where, in spite of Mehemet Ali's intercession, he and the companions who had followed him in his captivity were condemned to death, and after being paraded through the city with ignominy for three days were finally beheaded.
Further, there are elements of Islam, like the usages of the hajj (or pilgrimage to the sacred places at Mecca), the dryness of its official doctrine and the limitations of its real character as indicated in the Wahhabi revival, which so impair its apparent universalism that Kuenen found himself obliged to withdraw it from the highest rank of religions.
In 1824 Turki, son of the unfortunate Abdallah, headed a rising which resulted in the re-establishment of the Wahhabi state with Riad as its new capital; and during the next ten years he consolidated his power, paying tribute to and under the nominal suzerainty of Egypt till his murder in 1834.
In 1798 a Turkish force was sent from Bagdad into El Hasa, but was compelled to retreat without accomplishing anything, and its discomfiture added much to the renown of the Wahhabi power.
In the reign of Abbas, who succeeded Mehemet Ali, the Egyptian troops were driven from Nejd, and the Wahhabi state recovered its independence.
For a time it looked as if the supremacy of the Wahhabi empire was to be renewed; El Hasa, Harik, Kasim and Asir returned to their allegiance, but over Oman and Yemen Fesal never re-established his dominion, and the Bahrein sheiks with British support kept their independence.
In May 1814 Saud died, and his son,Abdallah, attempted to negotiate, but Mehemet Ali refused all overtures, and in January 1815 advanced into Nejd, defeated the Wahhabi army and occupied Ras, then the chief town in Kasim.
On the 14th of October 1802 the amir Abdul Aziz, at the age of eighty-two years, was murdered by a Shia fanatic when at prayers in the mosque of Deraiya, and Salad, who had for many years led the Wahhabi armies, became the reigning amir.
The Wahhabi War, indeed, dragged on till 1818, when Ibrahim (q.v.), the pasha's son, who in 1816 had driven the remnant of the Mamelukes into Nubia, brought it to an end.
