  The semileptonic $B_s (B) \to K_2^*(a_2, f_2) \ell\nu$, $\ell=\tau, \mu$
transitions are investigated in the frame work of the three-point QCD sum
rules. Considering the quark condensate contributions, the relevant form
factors of these transitions are estimated. The branching ratios of these
channel modes are also calculated and compared with the obtained data for other
approaches.
