Title:
Quran

Context:
Respect for the written text of the Quran is an important element of religious faith by many Muslims, and the Quran is treated with reverence. 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. Worn-out copies of the Quran are wrapped in a cloth and stored indefinitely in a safe place, buried in a mosque or a Muslim cemetery, or burned and the ashes buried or scattered over water.

Question:
What is done with the ashes of burned copies of the Quran?

buried or scattered over water
