Evidence from the text
The text itself measures the wrong: "They can never harm you, except by a nuisance" (3:111). Nuisance thus stops short of real damage. It names a burden of the body, in the head (2:196), menstruation (2:222), the rain that hinders carrying arms (4:102), and above all the word that wounds, of which one will hear "much nuisance" (3:186).
Minor, it is not for that light to bear. It goes with the denial of the messengers (6:34), with expulsion and exile (3:195); Moussa suffers it from his people (33:69, 61:5), the Informant from those who tarry in his house for discourse (33:53). The expected answer is patience: "We shall surely be patient in the face of the trouble you cause us" (14:12).
