I got a copy of the first edition of فتح المنان في نسخ القرآن by Ali Hasan Al-Areedh, supervisor of preaching at Al-Azhar. It is dated 1973 and is published by Al-Khanji Bookstore مكتبة الخانجي in Egypt.
He dedicated the book to "every free Muslim, protective of his religion, lover of the Quran and the truth, wanting to research and read for knowledge." I could've used that as dedication for readers of this forum
He stated repeatedly in the book that abrogation cannot be claimed without an authentic proof from the Quran or the Sunna. Yet, he goes on to find five cases
in which he asserts are abrogation cases, though he cannot furnish proof, only interpretation!
After finishing reading the book, it was obvious to me that Al-Areedh was struggling throughout his four-year study and throughout the pages of the book to reconcile his gut feeling that no abrogation exists in the Quran and the prevailing opinion of the scholars that it does. Many times he sounded like he was reassuring himself more than he was reassuring the reader.
He finishes his book saying the following,
وهذا ماثبت نسخه من آيات القرآن الكريم عندي واقتنعت به بعد وضوح الأدلة وظهور البراهين التي دلت عليها، وبقي القرآن الكريم محكما ثابتا أمام المعاندين والملحدين "لا يأتيه الباطل من بين يديه ولا من خلفه تنزيل من حكيم عليم"ـ
