What did the Prophet Muhammad (saw) say about those people who build places of worship over pious men's graves and paint pictures in it?
 Narrated `Aisha:                     Um Habiba and Um Salama mentioned a church they had seen in Ethiopia and in the church there were pictures. When they told the Prophet of this, he said, "Those people are such that if a pious man amongst them died, they build a place of worship over his grave and paint these pictures in it. Those people will be Allah's worst creatures on the Day of Resurrection . "
