Al-istinbatat al-wahiyah are fragile or imaginary deductions built on weak analogies, unverified reports or unsupported premises. Their language may sound argumentative, but either the premises are defective or the inference does not follow.
For example, “Most of this scholar’s judgments were sound, therefore every statement attributed to him must accord with revelation” is invalid. The first claim does not entail the second. Nor does an unreliable report become definitive divine law by repeated citation.
Reliable inference requires credible material, appropriate interpretive rules, relevant context and a defensible move from evidence to conclusion.
