فَأَلْهَمَهَا فُجُورَهَا وَتَقْوَاهَا
Then He inspired the soul with its wickedness and its piety. (Qurʾān 91:8)
The Qurʾānic use of ilhām rules out dismissing all inward awareness as an impossible notion. Yet the verse’s account of an implanted recognition of wrongdoing and piety is not equivalent to saying that every private impression supplies a new binding legal judgment.
One issue is the human capacity for moral recognition or warning. A different issue is whether a particular idea is actually correct rather than a product of desire or misunderstanding. Merely describing it as inspiration does not settle that second question.
