Contradiction is a sign of falsity

Muhammad Hizam's opinion regarding Al-Ibaanah before & after: Before: كتاب الإبانة فيه تأصيلات باطلة وقواعد باطلة كثيرة ومليئة بالأخطاء والقواعد المخالفة لمنهج السلف وزاد الكتاب فرقة بين أهل السنة والجماعة The Book Al-Ibaanah contains MANY false principles and is FULL of errors and principles contrary to the manhaj of the Salaf, and the book escalated division amongst Ahlus-Sunnah. After: فقد قرأت عما أثير على الشيخين الفاضلين ونظرت في الحجج التي يحتج بها كل طرف مستعينا بالله ومعتصما ومستهديا به فلم أر اختلافا في أصول السنة. I have read what was raised against the two virtuous sheikhs (I.e. Muhammad Al-Imaam and Al-Bura’ē), and I have looked at the arguments brought by both parties whilst seeking Allah's assistance and guidance and placing reliance on Him, and I have not seen there to be a differing concerning the principles of the Sunnah. Question: So when he previously said Al-Ibaanah contained MANY false principles CONTRARY to the manhaj of Ahlus-Sunnah, on what basis did he make such a bold judgement? Didn't he read the book? This is just one of many contradictions, listen to the above audio for more.
