I want to know the answer to the following question:
In what state are copies of the Quran sometime wrapped in cloth and buried?
All the background I'm provided with is that "Based on tradition and a literal interpretation of Quran 56:79 ("none shall touch but those who are clean"), some Muslims believe that they must perform a ritual cleansing with water before touching a copy of the Quran, although this view is not universal.". Is that enough to answer the question?
