Al ash-Sheikh

The Al ash-Sheikh (Arabic: آل الشيخ, ʾĀl aš-Šaykh), also transliterated in a number of other ways, including Al ash-Shaykh, Al ash-Shaikh, Al al-Shaykh or Al-Shaykh is Saudi Arabia's leading religious family. They are the descendants of Muhammad ibn Abd al-Wahhab. In Saudi Arabia, the family is second in prestige only to the Saudi royal family, the Al Saud, with whom they formed a power-sharing arrangement nearly 300 years ago. The arrangement, which persists to this day, is based on the Al Saud maintaining the Al ash-Sheikh's authority in religious matters and the Al ash-Sheikh supporting the Al Saud's political authority.

Although the Al ash-Sheikh's domination of the religious establishment has diminished in recent decades, they still hold most of the important religious posts in Saudi Arabia, and are closely linked to the Al Saud by a high degree of intermarriage. Because of the Al ash Sheikh's religious-moral authority, the arrangement between the two families remains crucial in maintaining the Saudi royal family's legitimacy to rule the country.
