It is not clear that the shooter was being at all guided by ISIS, or that he was engaged in prayers to Allah in the several hours before the sudden conversion to Martyrdom, via 911. Maybe he wasn't even passing out leaflets, even, or begging for money on the usual religious basis that money is really a curse in heaven(?)! Clergy and theologians of all faiths seem to understand that part. This doesn't at all look like anything usually regarded religious. Mainly it looks a lot like he suddenly decided to exit earth as somebody, nobody anymore. That is central to the secular lie of the propaganda organization, ISIS.
People from New York apparently find the propaganda easy to believe. One is running for US President, and seems to think that what happened in Orlando was a version of Moslem prayer, called religious.
"Crow, James Crow: Shaken, Not Stirred!"
(ISIS kill many Moslems to achieve their goals. Europeans find that to be a lot like Christian prayer where they are from!)
