This hadeeth comes under the following chapter: FORBIDDANCE TO BUILD MOSQUES ON THE GRAVES AND DECORATING THEM WITH PICTURES AND FORBIDDANCE TO USE THE GRAVES AS MOSQUES
'A'isha reported: Umm Habiba and Umm Salama made a mention before the Messenger of Allaah (sallAllaahu alayhi wa sallam) of a church which they had seen in Abyssinia and which had pictures in it. The Messenger of Allaah (sallAllaahu alayhi wa sallam) 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 Allaah.
