What are the most detailed books on death and its agonies, the world of Barzakh, and the Hereafter, that are based on the Qur'an and Sunnah in a scholarly manner?

Among the comprehensive books on the topics of death and the afterlife are: "Al-Tadhkirah bi Ahwal al-Mawta wa Umur al-Akhirah" by Al-Qurtubi, "Al-Ruh" and "Hadi al-Arwah ila Bilad al-Afrah" by Ibn al-Qayyim, "Ahwal al-Qubur" and "Al-Takhwif min al-Nar" by Ibn Rajab al-Hanbali. Also, the books by Ibn Abi al-Dunya: "Dhikr al-Mawt," "Al-Qubur," "Sifat al-Jannah," and "Sifat al-Nar." Additionally, "Sharh al-Sudur bi Ahwal al-Mawta wal-Qubur" by Al-Suyuti, "Ithbat Adhab al-Qabr" and "Al-Ba'th wal-Nushur" by Al-Bayhaqi, and "Al-Buhur al-Zakhirah fi Ulum al-Akhirah" by Al-Saffarini.

Care must be taken to acquire the verified editions of these books to ascertain the grade of the hadiths, as some of them contain weak or fabricated hadiths.

Among the good contemporary books in this field are those by Omar al-Ashqar: "Al-Qiyamah al-Sughra," "Al-Qiyamah al-Kubra," and "Al-Jannah wal-Nar."
