Are there comprehensive books on his Sunnah, may God bless him and grant him peace, and what are some of the books that can be referred to?

The primary books to consult for the Hadith of the Prophet, peace and blessings be upon him, are Sahih al-Bukhari and Muslim, followed by the four Sunan books (Sunan Abi Dawud, al-Nasa'i, Ibn Majah, and al-Tirmidhi), as well as Musnad Ahmad and Muwatta Malik. It is recommended to read them along with their commentaries, in addition to books of takhrij and verification like those by Al-Albani, and books that explain the hadiths of fiqh such as Nayl al-Awtar and Bulugh al-Maram, and books on Sirah (Prophetic biography) like Zad al-Ma'ad and Sahih al-Sirah al-Nabawiyah by Al-Omari.
