Al-tadhkīr bi-l-mawt wa-mā baʿdah includes the Qur'an's teaching on the end of worldly life and what follows.
Death: the close of earthly existence.
Resurrection and gathering: being raised and assembled.
Reckoning and balance: accountability and justice.
Paradise and Hell: the ultimate consequences of actions.
These teachings cultivate accountability, hope, reverence and moral reform. Details of the unseen should be affirmed to the extent supported by reliable revelation; speculative descriptions must not be mistaken for established interpretation.
