俱舍論記 6.44

6.44

「即由前說此亦無違」者，說一切有部答。即由前說一有一切有、一無一切無，互為因果理亦無違。

On "Precisely because of what was stated before, this too is not contradictory": this is the Sarvāstivādin answering. Precisely because of what was stated before—when one exists, all exist; when one is non-existent, all are non-existent—it is also not contradictory that they are mutually cause and effect in reason.
