Barzakh

Barzakh means a barrier or isthmus, something set between two things that keeps them from merging. The Qur'an uses it of the divide between fresh and salt water (25:53, 55:19-20) and once, decisively, of the state of the dead: those who ask to be returned to the world are told that "behind them is a barzakh until the day they are raised" (23:100). From that verse the tradition built its doctrine of the intermediate state, the interval between death and the general resurrection.

The content of that interval comes chiefly from hadith rather than the Qur'an: the questioning in the grave by two angels, commonly named Munkar and Nakir; the grave that is widened into a garden of the Garden for the believer or narrowed into a pit for the wicked; the soul's awareness of the living. Both Sunni and Shia traditions affirm an intermediate state, with Shia sources giving particular attention to the souls of the faithful gathered in the valley of peace.

Theologians differed over how literally to read it. Ash'ari scholarship generally affirmed the punishment and bliss of the grave as real and bodily; Mu'tazili theologians and later philosophically inclined writers tended toward figurative or spiritual readings, since the body visibly remains where it was buried. In Sufi metaphysics the word was generalised: Ibn Arabi made barzakh a technical term for any isthmus between two orders of being, and above all for the alam al-mithal, the imaginal world standing between pure spirit and dense matter, a usage that later shaped Persian illuminationist philosophy.

Belief in Munkar and Nakir's questioning in the grave generated concrete funerary customs across much of the Muslim world, intended to help or comfort the deceased through the barzakh's opening ordeal.

Talqin, instruction or reminding, is the practice, more common historically and still observed in some Sunni communities and widely among Shia Muslims, of a person present at the burial addressing the deceased after interment, reciting the profession of faith and reminding them of the correct answers to the questions the angels will ask, on the premise that the deceased retains some form of awareness capable of being reminded. The practice has drawn scholarly disagreement: some jurists regard it as well-attested and beneficial, while others, particularly in Salafi-oriented scholarship, consider the graveside formula weakly attested and prefer confining comparable acts to supplication for the deceased.

Recitation of the Qur'an, particularly Surat Ya-Sin, at the graveside or dedicated to the deceased's benefit afterward, is a broadly attested and much less disputed practice, resting on general hadith encouraging recitation for the deceased and on the wider principle that the living can transmit spiritual benefit to the dead through charity, supplication and recitation performed on their behalf, connected to disputes elsewhere in Islamic theology over the extent to which the dead can be reached by the actions of the living, a question that, like barzakh itself, receives more elaboration from later jurisprudence and popular practice than from the Qur'an's own comparatively spare eschatological statements.
