  In the paper, we construct eight color singlet-singlet type five-quark
currents with distinguished isospins to study the $\bar{D}\Xi^{\prime}$,
$\bar{D}\Xi_c^{*}$, $\bar{D}^{*}\Xi_c^{\prime}$ and $\bar{D}^{*}\Xi_c^{*}$
molecular states with strangeness via the QCD sum rules. Numerical results show
that the central values of the pentaquark masses with higher (lower) isospin
are slightly above (below) the thresholds of the corresponding meson-baryon
pairs, and support assigning the $P_{cs}(4459)$ as the $\bar{D}\Xi_c^{*}$
molecular state with the quantum numbers $IJ^P=0{\frac{3}{2}}^-$. The other
predictions can be confronted to the experimental data in the future.
