And Anas (may Allah be pleased with him) said that you are one who accompanies the funeral procession; you may walk in front of it, behind it, to its right, or to its left—you may walk on all sides. And other people besides Anas (may Allah be pleased with him) said that one should walk close to the funeral.

Narrated Abu Huraira: The Prophet said, "Hurry up with the dead body for if it was righteous, you are forwarding it to welfare; and if it was otherwise, then you are putting off an evil thing down your necks."
