Taking the Qur'an Into the Washroom
Question :
Is it permissible to take the Mushaf into the washroom?
Answer:
The people of knowledge say that it is not allowed to take the Mushaf into the Hammam, because the Qur'an deserves a form of reverence and respect which, as is well known, are violated by bringing it into such a place.
Question :
Is it permissible to take paper upon which Allah's Name is written into the washroom?
Answer:
It is allowed to enter the Hammam with papers containing Allah's Name as long as they are kept in one's pocket, without being exposed. There is some lenience here because there are many names that have Allah's Name in them, such as 'Abdullah and 'Abdul-'Aziz, etc.
