I came across this today and thought it would be good to pass on to others. I was not aware of Qureshi before today so I wanted to make sure he was the real deal. One can never be too sure about things found on the interwebs. There are some You Tube videos by Muslims discrediting this man, so that made me think that this may actually be worth considering. Qureshi is well recommended and indeed seems to be genuine. You can find his web site here.
Challies has a little biographical sketch of Nabeel here along with his plug for the book that he has written. Qureshi has written this book and it looks well worth reading.
