He, sallallaahu ‘alayhi wa sallam, explained creed-related mistakes people commit:
‘“When the Prophet of Allah, sallallaahu ‘alayhi wa sallam, became ill, some of his wives (who were next to him) talked about a church which they had seen in Ethiopia and it was called Mariya. Umm Salamah and Umm Habeebah had been to Ethiopia, and both of them narrated its (the church’s) beauty and the pictures it contained. The Prophet of Allah, sallallaahu ‘alayhi wa sallam, raised his head and said: “Those are the people who, whenever a pious man dies amongst them, make a place of worship at his grave and then they make those pictures in it. Those are the worst creatures in the Sight of Allah.””
Despite his illness, he, sallallaahu ‘alayhi wa sallam, did not let such an important issue pass without highlighting the mistake these people had committed. Rather he, sallallaahu ‘alayhi wa sallam, warned his wives and guided them to the path which would save them.
