How can I know every hadith of the Messenger of Allah, may Allah bless him and grant him peace, whether it is authentic (sahih), good (hasan), weak (da'if), or fabricated (mawdu'), in order to revive his Sunnah?

Shaykh al-Albani made efforts in serving the books of Sunnah and distinguishing the authentic from the inauthentic, including his service to the four Sunans, and his compilation of the verbal hadiths in "Sahih al-Jami' al-Saghir." Before studying the two Sahihs and the Sunans, it is recommended to study "Riyadh as-Salihin" and "Al-Adhkar" by An-Nawawi, "Umdat al-Ahkam" by Al-Maqdisi, and "Bulugh al-Maram" by Ibn Hajar. One should not abbreviate the salutation upon the Prophet, peace be upon him, with the letter (ص).
