The question/claim: "Does the Qur'an speak of punishment in the grave? On one reading, the detailed popular picture of 'grave punishment / life in the grave' — the interrogation by Munkar and Nakir, the squeezing of the grave, the bounty of the grave — is not Qur'anic text but an accumulation of hadith and earlier cultures. The word 'barzakh', in the death/afterlife context, occurs only once (23:100), and there it is not a place of punishment but a barrier/veil preventing the dead from returning to this world."
This objection is strong and deserves to be taken seriously: the Qur'an really does use 'barzakh', in the death/afterlife context, only once, in the sense of a 'barrier' (the word also occurs at 25:53 and 55:20, but there for the 'barrier' between two seas), and the details of the common grave-imagery are largely of narrative (hadith) origin. Yet the other side of the debate also has a point grounded in the text. Let us name both.
Context — which verses?
The debate turns on four verses:
"…behind them is a barzakh (barrier/veil) until the Day they are resurrected." (23:100 — wa min warāʾihim barzakhun ilā yawmi yubʿathūn)
"They are exposed to the Fire morning and evening (yuʿraḍūna ʿalayhā ghuduwwan wa ʿashiyyā); and on the Day the Hour arrives: 'Admit the people of Pharaoh into the severest punishment!'" (40:46)
"They will say: 'Our Lord, You caused us to die twice and gave us life twice…'" (40:11 — amattanā ithnatayni wa aḥyaytanā ithnatayn)
"(The people of Noah) were drowned, then admitted into a Fire (ughriqū fa-udkhilū nārā)…" (71:25)
Two readings
Classical / majority reading. The classical exegetical line treats 40:46 as the clearest textual proof of barzakh/grave punishment. Fakhr al-Dīn al-Rāzī and al-Shawkānī read the 'morning and evening exposure' as the souls being shown their place in Hell during the period between death and resurrection (ʿarḍ), while 'Admit Pharaoh's people into the severest punishment' at the Hour is a separate, greater punishment — so the verse shows a two-stage punishment (interpretation). Mujāhid, ʿIkrima and Muḥammad b. Kaʿb al-Quraẓī are also reported to take this verse as proof of grave punishment (interpretation). The Turkish Diyanet tafsīr, on the same line, reads 'morning and evening' as an idiom for the continuity of the punishment and a pointer to barzakh punishment (interpretation). In this picture the barzakh of 23:100 is also imagined as a place of waiting / reward-and-punishment alongside the barrier that blocks return (interpretation).
Qur'an-centred / academic reading. Mehmet Okuyan (Is there Punishment in the Grave according to the Qur'an?) foregrounds the text/interpretation distinction. For him the barzakh in 23:100 is not a place of punishment but a barrier/veil preventing return to this world (text). The 'two deaths – two lives' of 40:11 requires only two lives — this world and the Hereafter — and the text does not permit squeezing an independent 'life in the grave' in between (interpretation). The 'morning and evening' (ghuduwwan wa ʿashiyyā) of 40:46 is a this-worldly notion of time; since there is no day-and-night in that sense in the Hereafter, the 'exposure' can be read as the this-worldly, historical ruin of Pharaoh's people (famine, drowning in the sea, social-psychological collapse) (interpretation). On this reading the detailed grave-punishment picture is largely an accumulation of hadith and earlier culture (interpretation).
Honest limit
Where the objection is right. The Qur'an uses 'barzakh' three times in all, each time in the sense of a 'barrier/veil' (23:100; 25:53; 55:20); in the death/afterlife context it occurs only once (23:100), and it does not define it directly as a 'place of punishment'. Details such as the interrogation by Munkar and Nakir and the squeezing of the grave are of hadith origin, not textual. Okuyan's grammatical point — that 'morning and evening' is this-worldly time — is also serious.
But the text's own structure sets a limit. 40:46 narrates the 'morning-evening exposure' in contrast with 'the Day the Hour arrives' (yawma taqūmu al-sāʿa): the morning-evening exposure and the 'severest punishment' at the Resurrection are placed in two different times. This suggests, from the text itself, that the exposure is in a phase before the Resurrection (between death and rising) — a phase that overlaps with the barzakh of 23:100 (interpretation). So the idea of 'some kind of exposure/punishment in the barzakh' can be grounded not merely in hadith but in the internal structure of at least one verse.
Certain vs contested. Certain (text): barzakh = a veil blocking return (23:100); 40:46 distinguishes an 'exposure' specific to Pharaoh's people and a severer punishment at the Resurrection. Contested (interpretation): generalising this exposure as 'grave punishment' to all the dead, and the entire detailed popular picture. 71:25 and 40:46 are not decisive but open to a plural reading. The most honest position: the notion of barzakh / barzakh-exposure has a minimal trace in the Qur'an, while the detailed picture of common 'grave punishment' belief is largely an accumulation of interpretation and narration.
Note: the claim that reading 40:46 as proof of grave punishment is 'the consensus of all scholars', and the verbatim verification of the Mujāhid/ʿIkrima/Muḥammad b. Kaʿb attributions from classical texts (e.g. al-Ṭabarī), could not be fully fixed in this compilation and are relayed with caution.
