Analysis of information sources in references of the Wikipedia article "Səudiyyə Ərəbistanında erkən islam abidələrinin dağıdılması" in Azerbaijani language version.
The tension between Saudi Shi'ite and Wahhabi is especially intense because Saudi "Wahhabis" actively reject all veneration of man, even the prophet. At one point, they even attempted to destroy Muhammad's tomb in Medina. In contrast, the Saudi Shi'ites are "Twelvers," a branch of Islam that venerates the Prophet's son-in-law Ali, and believes that the leadership of Islam must pass through Ali's line. They venerate each of the past imams, and make pilgrimages to their tombs.
