Muwatta Malik 574

Yahya related to me from Malik from Muhammad ibn Amr ibn Halhalaad-Dili from Mabad ibn Kab ibn Malik that Abu Qatada ibn Ribi used to relate that a funeral procession passed by the Messenger of Allah, may Allah bless him and grant him peace, and he said, "One is relieved and another others are relieved from." They said, "Who is the one relieved and the one from whom others are relieved?" He said, "A slave who is mumin is the one who is relieved from the exhaustion and suffering of this world to the mercy of Allah, and a wrong-acting slave is the one from whom people, towns, trees and animals are relieved
