  We find a very strong correlation between the intrinsic spectral slope in
X-rays and the amount of Compton reflection from a cold medium in Seyfert AGNs
and in hard state of X-ray binaries with either black holes or
weakly-magnetized neutron stars. Objects with soft intrinsic spectra show much
stronger reflection than ones with hard spectra. We find that at a given
spectral slope, black-hole binaries have similar or more reflection than
Seyferts whereas neutron-star binaries in our sample have reflection consistent
with that in Seyferts. The existence of the correlation implies a dominant role
of the reflecting medium as a source of seed soft photons for thermal
Comptonization in the primary X-ray source.
