What are the reliable books that can be used to understand the consensus of the Companions and the Seven Jurists of Medina, so as to deduce legal rulings from them?

Books that deal with the biography and narratives of the Companions differ from books that deal with their jurisprudential opinions.

Among the biographical works are: "Hilyat al-Awliya", "Sifat al-Safwah", "Al-Siyar" by Al-Dhahabi, "Al-Bidaya" by Ibn Kathir, and "Al-Isabah" by Ibn Hajar.

As for books containing their jurisprudential sayings, consensus, and differing opinions, these include: "Al-Tamheed" by Ibn Abd al-Barr, "Sunan al-Bayhaqi", "Al-Muhalla" by Ibn Hazm, "Al-Ishraf" and "Al-Awsat" by Ibn al-Mundhir, "Musannaf Abd al-Razzaq", "Musannaf Ibn Abi Shaybah", and "Al-Ijma'" by Ibn al-Qattan. These are also found in the books of great imams such as Al-Nawawi, Ibn Qudamah, and Ibn Taymiyyah, as well as the sayings of the seven jurists of Medina.
