I did a Google search on the phrase “Mr. Obama recalled the opening lines of the Arabic call to prayer, reciting them with a first-rate accent. In a remark that seemed delightfully uncalculated”
First hit is this link (add http in front of it)

And the rest of the quote is there also:
..., Mr. Obama described the call to prayer as one of the prettiest sounds on Earth at sunset.
Other places it is mentioned: (again, add http in front)

and the part in between the two quotes is “(it’ll give Alabama voters heart attacks)”

another interesting snippet from the above article is a quote from 0
“I was a little Jakarta street kid”
Hmmmm...
