Q: I happened to go to a musalla a few weeks ago. There is a courtyard separating the wudhu khana and the Salaah area. There was a lot of rain and it flooded the courtyard. People walked through to get onto the carpeted area. As I walked through, I had seen the droppings of fouls in the water which others also walked through onto the carpet. Others may have not seen it.
