What did the Prophet Muhammad (saw) say about those who decorated their places of worship with pictures?
 'A'isha reported:                      Umm Habiba and Umm Salama made a mention before the Messenger of Allah (may peace be upon him) of a church which they had seen in Abyssinia and which had pictures in it. The Messenger of Allah (may peace be upon him) said: When a pious person amongst them (among the religious groups) dies they build a place of worship on his grave, and then decorate it with such pictures. They would be the worst of creatures on the Day of judgment in the sight of Allah.
