Telling the people who are well established in jurisprudence and modernization as much

Translation

A book that examines the science of abrogating and abrogating hadiths. The author compiled it after seeing the confusion in this art among the ancients, and he limited it to the hadiths whose abrogation was correct or plausible, and they amounted to twenty-one hadiths, while turning away from what had no basis for abrogation, so that it would be a hasty resource for the memorizer.
