  "abstract": "The current knowledge on the $D_{s}^{\\ast}$ meson are very limited. Besides the dominant electromagnetic decays, the $D_{s}^{\\ast}$ weak decays are legal and offer the valuable opportunities to explore the wanted $D_{s}^{\\ast}$ meson. In this paper, the $D_{s}^{\\ast}$ ${\\to}$ ${\\phi}{\\pi}$ decay was studied with the PQCD approach. It is found that the branching ratio ${\\cal B}(D_{s}^{\\ast}{\\to}{\\phi}{\\pi})$ ${\\sim}$ ${\\cal O}(10^{-7})$, which corresponds to several thousands of events at the $e^{+}e^{-}$ collider experiments including STCF, SuperKEKB, CEPC and FCC-ee, and several millions of events at the hadron collider experiments, such as LHCb@HL-LHC. It is feasible to experimentally study the $D_{s}^{\\ast}$ ${\\to}$ ${\\phi}{\\pi}$ weak decay in the future.",
