  The rare semileptonic $\chi_{c1}(1p)\rightarrow D_{s}^{+}e\bar{\nu }$ decay
is analyzed, by using the three-point QCD sum rules. Taking into account the
two-gluon condensate contributions, the transition form factors related to this
decay are calculated and are used to determine the total decay width and
branching fraction. Our findings may be approved by future experiments.
