Ibn Hazm Al-Andalusi writes that the part
ولا يحل لكم أن تأخذوا مما آتيتموهن شيئا (And it is not lawful for you to take anything of what you have given them) in
was abrogated by the subsequent exception
إلا أن يخافا ألا يقيما حدود الله (unless both fear that they will not be able to keep [within] the limits of God).
The majority of scholars have agreed that exceptions are not abrogation. In fact, Ibn Hazm was one of those scholars!
Abu-`Ubayd Al-Qaasim ibn Salaam did the same thing in his book الناسخ والمنسوخ في القرآن والسنة, pages 98-111. He quoted Ibn Abbaas saying that this was a case of exception, yet Ibn Salaam called it a case of naskh. Clearly, he, as many others have done, understood naskh in its general meaning as amendment, not restricted to the specific meaning of abrogation.
