There are some narrations reported from the generation that followed the Companions (i.e. the Taabi'is) which were attributed to the Prophet referring to poetry as the devil's Quran.
Moreover, when Abu Bakr once entered on his daughter 'Aa'ishah on an 'Eed day and found two slave girls singing, he said: "Do I hear the devil's trumpets in the house of the Prophet ?" [Al-Bukhari]
As regards the statement of the Shaykh "The satan's place is the bathroom", then this is true, for the devils haunt such impure places. The Prophet used to say whenever he entered the lavatory: "O Allaah! I seek refuge in You from the male and female devils.”
Besides, the Prophet said: "Verily these places are haunted (by devils), so if any of you enter the lavatory, let him say: 'O Allaah, I seek refuge in You from the male and female devils.' " [Ahmad, Abu Dawood and others]

Allaah Knows best.
