Sayyiduna Abdullah bin Abbas and Sayyidah Aisha (may Allah be pleased with them both) narrate that when the Messenger of Allah (peace and blessings be upon him) was near death, he would cover his face with a sheet, and whenever he felt difficulty in breathing, we would lift the sheet from his face. In this state, the Prophet (peace and blessings be upon him) said: "May Allah curse the Jews and Christians; they made the graves of their prophets into places of worship." Sayyidah Aisha (may Allah be pleased with her) says: (In fact) the Prophet (peace and blessings be upon him) was warning people against doing what they did.
