Wahhabi movement
The Wahhabi movement was heavily influenced by the works of the medieval Hanbali theologian Ibn Taymiyyah who was considered by them to be the "ultimate authority on a great number of issues". One of these issues was the position on the visitation of the Prophet's tomb. According to Ibn Taymiyyah all the "ahadith" encouraging the visitation of the Prophet's tomb are fabricated ("mawdu‘"), are not contained in the six main collections of "hadith" or "Musnad Ahmad ibn Hanbal", and violate "tawhid al-uluhiya".
