Does the deceased remember worldly matters, and will the martyr wife recognize her husband in the Afterlife?

The conditions of the deceased in their grave are part of the unseen (Ghayb), and there is no evidence to suggest that they recall worldly matters like markets and streets. What is established is that the deceased in their grave will be questioned about their good or bad deeds, and their bliss or torment, in accordance with the texts. Similarly, it is established that the souls of the believers will question those who come after them about the people of this world.

As for a woman's marriage in the Hereafter, it includes the martyr and others.
