Re: Putting the Noble Quran on the floor of a mosque
Yes, that's true. Zaban is always paq, wether or not you've performed wudhu.
By putting it somewhere high I don't mean forgetting it.
But it's true we should read it more often and try to understand what it says.
(I looked up the aya's for the commentary in my Quran, and it is Surah al_Waqiah, Surah at_Tahrim is no. 66)
