When I am reading the Quran and have it spread on the floor I am respecting it more than having it sitting collecting dust on the table. To say that I am disrespecting the Quran while I am reading it because I have it on the ground, without evidence, is wrong. I think When someone comes by and interrupts me to tell me to lift the book off the ground they are disrespecting me not preventing me from disrespecting the Quran.
