`Aisha and `Abdullah bin `Abbas said, "When Allah's Messenger (ﷺ)
became ill seriously, he started covering his face with his woolen sheet, and when he felt short of
breath, he removed it from his face and said, 'That is so! Allah's curse be on the Jews and the
Christians, as they took the graves of their prophets as (places of worship),' intending to warn (the
Muslims) of what they had done."
Sahih al-Bukhari Book 64, Hadith 464
