“Those of your women who commit indecency ...” (al-Nisāʾ 4:15) discusses an earlier regulatory response, including confinement until a further way is established. Later passages in Sūrat al-Nūr and relevant Prophetic explanation describe the legal response in a developed form.
The phrase “or Allah makes a way for them” already points toward a forthcoming determination. This makes the case materially different from a merely apparent contradiction: the earlier arrangement is itself framed as provisional.
The legal interpreter must therefore distinguish a provisional measure giving way to a later ruling from a simple exception or semantic clarification.
