Sayyidah Aishah (may Allah be pleased with her) said: When the Messenger of Allah (peace and blessings be upon him) fell ill, some of his wives were talking about a church in the land of Abyssinia called Mariyah. Umm Salamah and Umm Habibah (may Allah be pleased with them both) had come from Abyssinia, and they mentioned its beauty and its images (decorations). The Prophet (peace and blessings be upon him) said: "Indeed, when a righteous man among them died, they would make his grave a place of prostration, then they made these images in it. These are the worst of creation in the sight of Allah."
