Tomb

Muhammad was buried where he died in Aisha's house. During the reign of the Umayyad caliph al-Walid I, al-Masjid an-Nabawi (the Mosque of the Prophet) was expanded to include the site of Muhammad's tomb. The Green Dome above the tomb was built by the Mamluk sultan Al Mansur Qalawun in the 13th century, although the green color was added in the 16th century, under the reign of Ottoman sultan Suleiman the Magnificent. Among tombs adjacent to that of Muhammad are those of his companions (Sahabah), the first two Muslim caliphs Abu Bakr and Umar, and an empty one that Muslims believe awaits Jesus.

When Saud bin Abdul-Aziz took Medina in 1805, Muhammad's tomb was stripped of its gold and jewel ornamentation. Adherents to Wahhabism, Saud's followers, destroyed nearly every tomb dome in Medina in order to prevent their veneration, and the one of Muhammad is reported to have narrowly escaped. Similar events took place in 1925, when the Saudi militias retook—and this time managed to keep—the city. In the Wahhabi interpretation of Islam, burial is to take place in unmarked graves. Although the practice is frowned upon by the Saudis, many pilgrims continue to practice a ziyarat —a ritual visit—to the tomb.
