Taking cell-phones on which Qur’aan has been recorded into the washroom

Recently electronic devices and cell phones have become widespread, and it is possible to store audio recordings of the Qur’aan in them. What is the ruling on taking such devices into washrooms?

Praise be to Allaah.
It is not haraam to take these cell phones into washrooms because they do not come under the same rulings as the Mus-haf (printed copy of the Qur’aan), even after Qur’aan has been recorded in them, because it is sound which is hidden inside it, it is not writing that is visible. And Allaah knows best.
