Is the book "Al-Isti'dad li Yawm al-Jaza'" by Ibn Hajar al-Asqalani, which contains unverified hadiths and narrations, known to you, and how should one deal with it?

After researching the works of Al-Hafiz Ibn Hajar Al-Asqalani, no book titled "Al-Isti'dad li Yawm al-Ma'ad" (Preparation for the Day of Return) was found. Contemporary researchers have warned against attributing this book to him, affirming that it has been falsely printed and ascribed to him, and that it contains fabricated hadiths. Sheikh Mashhoor Hasan Salman confirmed this, pointing out that Ibn Hajar himself described a similar book as "Hatib Layl" (a night gatherer of wood), full of fabricated falsehoods. Furthermore, Dr. Shakir Mahmoud Abd al-Moneim denied the attribution of the book to Ibn Hajar for several reasons, including the difference in its style, the absence of mention by his contemporary sources, and the lack of the author's name on most manuscripts. The verifier, Adel Abu al-Ma'ati, who verified the book, confirmed that it is not mentioned in the authoritative biographical works on Ibn Hajar, and that the printed editions differed in their attribution to him.
