Um Habiba and Um Salama mentioned about a church they had seen in Ethiopia in which there were
pictures. They told the Prophet (ﷺ) about it, on which he said, "If any religious man dies amongst those
people they would build a place of worship at his grave and make these pictures in it. They will be the
worst creature in the sight of Allah on the Day of Resurrection."
Sahih al-Bukhari Book 8, Hadith 77
