A classical question due to Yoneda is, “When is the tensor product of any two injective modules injective?” Enochs and Jenda gave a complete and explicit answer to this question in 1991. Since $RD$-injective modules are a generalization of injective modules, it is natural to ask whether the tensor product of any two $RD$-injective modules is $RD$-injective. In this paper we deal with this question.
