Suppose someone swears, “I will not eat this tree.” In the ordinary sense of eating food, one cannot literally eat the tree as such. Its produce, such as fruit, becomes a sensible intended object.
«حقيقة متعذرة»
A literal meaning whose fulfilment is impossible.
A figurative reading is possible because the tree is related to its fruit as producer to product. Whether consuming the relevant fruit breaches the oath follows from this interpretive choice. The figurative reading rests on an impossible literal performance and a real semantic link, not on preference alone.
