Anyway, the mirror is flat, so its "focal length" is infinity, i.e. it
has no effect on the image, other than reflecting it in the plane of the
mirror. So the distance to the minaret is the distance from the camera
to the mirror, plus the distance from the mirror to the minaret. This is
a lot further than the distance from the camera to the mirror, which is
why you don't get them in focus at the same time.

So the only way to get them both in focus in one shot is to use a large format camera that stops down to f/64 to get the maximum hyperfocal range.
