Funerals (Al-Janaa'iz)
Bukhari :: Book 2 :: Volume 23 :: Hadith 378
Narrated Al-Mughira:
I heard the Prophet saying, "Ascribing false things to me is not like ascribing false things to anyone else. Whosoever tells a lie against me intentionally then surely let him occupy his seat in Hell-Fire." I heard the Prophet saying, "The deceased who is wailed over is tortured for that wailing."
