«قَدْ كَانَ مِنْكَ مَا يُؤْلِمُ»
Something has come from you that causes pain.
With no expressed object for «يؤلم», the hurt is not restricted to one named recipient. In a context of strong complaint, the utterance may suggest that many can be affected; this is rhetorical generalization through non-specification.
Yet silence about an object does not mechanically entail the logical quantifier “everyone.” “It causes pain” and “It pains every person” are not identical claims; the breadth of the intended reading is regulated by context and usage.
