Below are two debates of mine that I have done on the subject of the doctrine of the Trinity vs. the Islamic concept of Tawhid (oneness of Allah). The first of these aired on Premier Christian Radio in the UK back in May of last year. My opponent was Abdurraheem Green, director of the Islamic Education and Research Academy (IERA).
The second one is a more recent debate, with a formal structure, which took place in London in August of 2015. My opponent was Muslim scholar Dr. Shabir Ally, president of the Islamic Information and Dawah Centre International in Toronto. For my responses to commentary on this debate by Ijaz Ahmed of Calling Christians, see my articles here and here.
