What do the Qur'an and the narrations of the Ahl al-Bayt actually disclose about the heavens, their inhabitants, and the paths between Earth and the higher realms?

Inhabitants of the Heavens reconstructs a careful map of the unseen world from the transmitted sources themselves. It examines the seven heavens, their gates and inhabitants, the angels and the Spirit, the Frequented House, Sidrat al-Muntaha, the Kursi and the Throne, the Miʿraj, the ways of ascent, the folding of distance, time between worlds, and the descent of Command to Earth.

Rather than forcing revelation into modern astronomy?or reducing the unseen to metaphor?the book follows a stricter method: where the evidence establishes a connection, it is drawn; where the evidence is probable or possible, that distinction remains visible; and where the texts do not disclose an answer, the map leaves an honest blank.

Drawing extensively on the Qur'an and classical Imami sources, the study also distinguishes between knowledge, permission, capacity, authority, and execution, while maintaining a clear theological boundary throughout: every rank, power, and function described belongs to creation and remains dependent upon God.

The result is not an encyclopedia of angels, but a structured investigation into the architecture of the unseen and the relationship between heaven, Earth, ascent, descent, and divine Command.
