Vladimir Putin’s supposed speech to the Duma on minorities and sharia law

A widely circulated email claims that, in a speech to the Duma on 14 February, Vladimir Putin bluntly advised Russian minorities that they should speak Russian and adapt to Russian culture if they wish to live in the country and that, if they prefer sharia law, they should go and live somewhere else.

Did Putin make such a speech? Hoax-Slayer thinks not.
