  The flavor anomalies reported in $R_K$, $R_{K^*}$, $P_{5}^{\prime}$ and
$\mathcal{B}(B_s\, \to\, \phi\, \mu^+\, \mu^-)$ indicate lepton flavor
universality violation in $b \to s\,l^+\,l^-$ quark level transition decays.
The deviation from the SM prediction reported in the underlying flavor
observables currently stand at the level of $2.5\sigma$, $2.4\sigma$,
$3.3\sigma$ and $3.7\sigma$, respectively. In this context, we perform an
angular analysis of the four-body differential decay of $B_s\, \to\,
f_{2}^{\prime}\,(1525)\,(\to K^+\,K^-)\,\mu^+ \,\mu^-$ in a model independent
effective field theory framework. The decay mode $B_s\, \to\,
f_{2}^{\prime}(1525)\,l^+\,l^-$ undergoes similar $b \to s$ neutral current
quark level transition and, in principle, can provide complementary information
regarding lepton flavor universality violation in $b \to s\,l^+\,l^-$ quark
level transition decays. We give predictions of various physical observables
such as the branching ratio, the longitudinal polarization fraction, the
forward-backward asymmetry, the angular observables $P_1$, $P_2$,
$P_{4}^{\prime}$, $P_{5}^{\prime}$ and also the lepton flavor sensitive
observables such as the ratio of branching ratio $R_{f_{2}^{\prime}}$,
$Q_{F_L}$, $Q_{A_{FB}}$, $Q_{1}$, $Q_{2}$, $Q_{4}^{\prime}$, $Q_{5}^{\prime}$
for $B_s\, \to\, f_{2}^{\prime}\,(1525)\,(\to K^+\,K^-)\,\mu^+ \,\mu^-$ decays
in the standard model and in the presence of several 1D and 2D new physics
scenarios.
