  We study the nonleptonic charmless $B_{u,d,s} \to K_0^*(1430)P$ $(P=K\,,
\pi)$ and $ K_0^*(1430)V$ $ (V=K^*\,, \rho\,, \omega\,, \phi)$ decays. The
amplitudes are calculated within the QCD factorization, and the
non-perturbative quantities are evaluated by using a covariant light-front
approach. The branching fractions and CP asymmetries of theses decay modes are
calculated, some decay modes are first predicted, and some useful relations
based on $SU(3)$ flavor symmetry are discussed. Comparing the theoretical
results with the current available experimental data, it is found that
$K_0^*(1430)$ can be described as the lowest-lying p-wave $(s,u/d)$ state
rather than the first excited one.
