Re: Putting the Noble Quran on the floor of a mosque
The Indian-Subcontinent Version of Islam (IVI) puts a lot of burden on the logistical aspect of Quran, its not that we should intentionally try to disrespect the book, be that any book, but we just have to make sure that the message in the book is always more important than the "Kurrsi" and "Green lace wala ghulaf" or having Quran collecting dust on the highest shelf.
In our school there was a big debate when it was allowed for students to write on their copies of Quran, I personally thought that it helped the students mark important Ayas and chapters and enhanced their understanding and familiarity with Quran. But then there were the IVI teachers who though that it was disrespectful.
