If a man divorces his wife before consummation, must she begin a new Iddah period if he remarries her and divorces her again?

Primary text

There are two narrations regarding whether she must start a new Iddah after the second divorce if the first divorce occurred before consummation. One narration states a new Iddah is required, aligning with the view of Abu Hanifa, because any divorce that necessitates an Iddah requires a fresh commencement. The second narration states that a new Iddah is not required, which is the view of Al-Shafi'i and Muhammad ibn al-Hasan. This second view relies on the general ruling that divorce before consummation does not entail an Iddah, citing the Quranic verse: {And if you divorce them before you have touched them, then there is for you no prescribed period concerning them} (Quran 33:49).
