In 1349 a great part of Maimand and of three little villages belonging to it became wakf (pious endowment) of the shrine at Shiraz of Mir Ahmed, surnamed Shah Chiragh, a son of Musa Kazim, the seventh imam of the Shiahs, and the remainder of the Maimand grounds was given to the shrine by Mir Habbib Ullah Sharifi and by Shah Ismail in 1504; the administration of the Maimand property as well as the guardianship of the shrine is still with the descendants of Mir Habbib Ullah.
Shiahs predominate on the Persian coast except in the districts of Rud Hilleh, Shibkuh, Lingeh, Bastak, Biyaban, Jask, and on the islands of the Persian Gulf.
In the territory controlled by the Emir of Nejd the official religion is Wahabi, but a few Shiahs are still to be found in the districts of El Hasa and Hofuf.
Panislamic ideas have obtained little hold in this region; in Persia and wherever people are Shiahs the pretensions of the Sultan of Turkey to the headship of the Mahommedan world are rejected, as also in Oman, where the bulk of the population are Ibadhi.
The vast majority of Afghans are of the Sunni sect; but there are, in their midst, such powerful communities of Shiahs as the Hazaras of the central districts, the Kizilbashes of Kabul and the Turis of the Kurram border, nor is there between them that bitterness of sectarian animosity which is so marked a feature in India.
In India the Sunnis greatly preponderate, but they usually share with the Shiahs their veneration for Hasan and Husain and strictly observe the Mohurrum.
