Wadi Al-Salam cemetery is also the only cemetery in the world where the process of burial is still continuing to day since more than 1,400 years.
The graveyard holds importance in Shiite belief as it has been said that the souls of all faithful men and women shall be moved there, no matter where their bodies have been buried.
Many prophets, kings, princes and Sultans lie in this cemetery including that of Prophet Hud, Prophet Saleh, and Ayatullah Sayyid Muhammad Baqir al-Sadr, as well as the remains of the prince of faithfuls, Ali Ibn Abi Talib.
