The Virtues of Attending the Jannaza

There's a famous narration from Abdullah of Nrudhi Allahu Anhuma. He used to follow the footsteps of the Prophet Salallahu Alaihi Wasallam. Whoever witnesses the Jannaza and then follows it until that person is buried will get two kirat, two mountains. If you go through to the Jannazaar and you witness the burial as well, then you get two Asgara Huma, mithru Ughat.
