Abstract The spacetime solution for a black hole, surrounded by an exotic matter field, in Rastall gravity, is calculated in an arbitrary d-dimensional spacetime.After this, we calculate the scalar quasinormal modes of such solution, and study Apron the shift on the modes caused by the modification of the theory of gravity, i.e., by Pour Over Dripper the introduction of a new term due to Rastall.We conclude that the shift strongly depends on the kind of exotic field one is studying, but for a low density matter that supposedly pervades the universe, it is unlikely that Rastall gravity will cause an instability for the probe field.
