What are the books in which Al-Albani classified the hadiths of the Four Sunan, such as a hadith in Sunan An-Nasa’i, to clarify its degree?

Shaykh Al-Albani's project, "Taqrib al-Sunnah Bayna Yaday al-Ummah" (Bringing the Sunnah Closer to the Ummah), aims to facilitate access to the well-known collections of Sunnah by removing the chains of transmission (asanid) and retaining only the texts (mutun) along with a judgment on their authenticity. This project covered the four Sunan books, dividing them into two categories: authentic (sahih) and weak (da'if), while preserving the original order of the hadiths. He also worked on other collections such as "Sahih Ibn Hibban," "Al-Adab Al-Mufrad," "Al-Targhib wa'l-Tarhib," and "Al-Jami' al-Saghir." He has other detailed books on judging hadiths, such as "Silsilat al-Ahadith al-Sahiha wa'l-Da'ifa" (Series of Authentic and Weak Hadiths) and "Irwa al-Ghalil," which authenticates hadiths related to rulings. His works are available in digital programs and hadith encyclopedias.
