Re: Obama quoting the hadith.... tomorrow, Insh' the world will quote the Quran!

I personally think it's a goodwill gesture, and to give the impression of a warm new start with Obama Presidency. Because much of the world was and continues to watch what he does. So he's making sure he doesn't leave any one group/faith/religion behind in this "We are all fighting our cause" kinda thing.
