What are the comprehensive collections of Hadith relied upon by Sunnis today, and what is their status and the reasons for it?

There is no single comprehensive book containing all the Hadiths of the Messenger of Allah, may Allah's prayers and peace be upon him, but they are preserved in the collections of Sunnah. Among the comprehensive books that contain many Hadiths are: "Jami' al-Jawami'" by Al-Suyuti, "Kanz al-'Ummal" by Al-Muttaqi al-Hindi, and "Jami' al-Usul" by Ibn al-Athir, which compiled the six books. Among the best contemporary books is "Al-Musnad al-Jami'". The books of Shaykh al-Islam Ibn Taymiyyah are considered authoritative by the Ahl al-Sunnah. The most authentic of the Sahih books are "Sahih al-Bukhari" and "Sahih Muslim," followed by "Sahih Ibn Khuzaymah" and "Sahih Ibn Hibban." Among the most famous Musnads are: "Musnad al-Imam Ahmad," "Musnad Abi Hanifah," "Musnad al-Bazzar," "Musnad Abi Ya'la al-Mawsili," and "Musnad al-Humaydi."
