This is the third in a series of 'challenges' I have presented to our brothers from Ahlul Sunnah. (1) http://www.shiachat.com/forum/topic/235021910-a-massive-challenge-to-absolutely-every-sunni/ (2) http://www.shiachat.com/forum/topic/235022032-another-massive-challenge-to-all-sunnis/ So far, no one has been able to adequately refute either of them and I welcome any Sunni brothers to attempt it. In this one, I want to discuss the dust or stone that we prostrate on, and whether that is the innovation or praying on carpets is the innovation, I'm sure everyone is familiar with Ibn Taymiy
