Given the obsession with hard (in fact over-) work in the English-speaking world and European north tends to be commonly treated as an artifact of the "Protestant work ethic" this seems pretty off-base.
Ironically, through the last century, there is a "modern" Islamic speech that preaches "hard work ethics" (the western way) among other western values. It will be funny if the west starts to morally rethink their life style, while the Islamic world is about to complete the low-morale modernization process.
Except for those nations sitting on abundant oil reserves, the Muslim world is chaotic, unproductive and has terrible human rights / freedom of expression.
But that's also like blaming Christianity for the problems in Central America or Central Africa. Religion is only a small factor.
