In this paper, we generalize
the following inequality due to N. Bebiano et al which states that for

The above inequality gives a reverse weighted mixed Schwarz inequality. Also, we prove some reverse inequalities for indefinite inner product space. Moreover, we establish some refinements for
the reverse of Schwarz inequality as well.
