Mishkat al-Masabih #1660

Abu Musa said he heard God’s messenger say, “If anyone dies and the mourner gets up and says, ‘Alas for the mountain! Alas for the chief!’ and such like, God will put two angels in charge of him who will beat him on the breast and ask him whether he was like that.” Tirmidhi transmitted it, saying this is a gharib hasan tradition.
