Recently, Onari and Kontani submitted a paper [arXiv:1105.6233] which criticizes our recent theoretical study [arXiv:1103.0586] on the neutron scattering experiment as a probe for determining the superconducting gap in the iron pnictides. In their paper, Onari and Kontani have developed a formalism in which the imaginary part of the dynamical spin susceptibility (Im$\chi_s(\Vec{q},\omega)$) in the superconducting state can be more accurately calculated especially in the $\omega<2\Delta$ regime, where $\Delta$ is the superconducting gap. In section IIIC of their paper, they mention that the conclusions of our paper are "incorrect based on inaccurate numerical calculation". In the present Comment, we show that this in fact is not correct.
