Wadi-us-Salaam, which means Valley of Peace, is the world's largest cemetery.

More than 6 million people are buried here, and many Shiites from all over the world have the same wish.

Najaf is believed to be a piece of heaven on earth as mentioned by the cousin of the prophet Muhammad, Imam Ali, who is also buried here. Furthermore, it is believed that he will intercede for his followers such that they will one day be raised from the dead together with their leader.
