The matter isn't moving. Space is expanding, ie, space is being inserted in-between all bits of matter. Edit: To elaborate further: Since all the newly expanded space also expands, the distance to travel continuously increases as the light travels, to the point where over a certain distance the light never completes the journey. So, the net effect is that the two objects become further apart faster than c, even though neither of them are moving.
