It was written in "History of the Wahhabis" by the Ottoman naval commander Ayoub Sabri: Saud bin Abdul Aziz sent his conditions to the people of Medina upon surrounding their city in the early eighteenth century, saying: Article I: worshipping God should be according to the provisions and beliefs of the Wahhabi religion. Article IV: Wahhabi religion and its provisions should be embraced instead of the religion of your forefathers which should be abandoned.
