`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."
