Is it possible to prepare an authentic version of the book "Riyadh as-Salihin" by replacing the weak hadiths with authentic hadiths within their respective chapters, along with the question of whether it is necessary to change the book's name or simply suffice with a disclaimer about the changes?

The author of "Riyad al-Salihin" committed to mentioning only authentic hadiths. Scholars have served this book through commentaries, abridgments, and verifications. Verifiers have pointed out any weak hadiths found within it, and the Ummah has accepted it. Therefore, it is recommended to serve other books that have not received the same level of service. However, if no other book is available, there is no religious impediment to working on this book, perhaps naming the work "Sahih Riyad al-Salihin," for example. This, however, requires knowledge and discernment between authentic and weak narrations.
