al-Aḥzāb 33:7-8

Wa idh akhadhnā mina'l-nabiyyīna mīthāqahum wa minka wa min Nūḥin wa Ibrāhīma wa Mūsā wa ʿĪsa'bni Maryam, wa akhadhnā minhum mīthāqan ghalīẓā · Li-yasʾala'l-ṣādiqīna ʿan ṣidqihim, wa aʿadda li'l-kāfirīna ʿadhāban alīmā

"And when We took from the prophets their pledge, and from you, and from Noah (Nūḥ), Abraham (Ibrāhīm), Moses (Mūsā) and Jesus (ʿĪsā) son of Mary (Maryam). We took from them a firm pledge. · So that He may ask the truthful about their truthfulness. And He has prepared for the disbelievers a painful punishment."

On a first reading these two verses look unconnected with the five that precede them. After a regulation about adoption and kinship there is a sudden move to a pledge taken from the prophets.

The link lies in the concept of "the word given", and its function within the flow of the sūra is this:

The fourth and fifth verses said that the word that comes out of a man's mouth makes nothing real. The seventh verse shows when a word is binding: when the party who takes it is God, and when the word is ghalīẓ (heavy, firm).

That is, the sūra does not devalue the spoken word; it settles when a word is weighty. I record this as my own reading.

And there is a second link as well: a pledge given will be recalled in the siege section (verse 15) — "they had earlier given God their pledge: that they would not turn their backs." The seventh verse lays the ground for that reminder. The sūra begins the giving of pledges with the prophets and brings it down to the believers.

To trust, to be firm, to bind. Wathīqa — a document; withāq — a bond, a strap; mīthāq — an agreement made fast.

The concrete sense of the root is a bond — and this agrees with the whole web of "bonds" in the sūra: the tie of lineage (4-5), the tie of kinship (6), the tie of a pledge (7).

غَلِيظ — root غ-ل-ظ. Its concrete sense is thickness, hardness: what is not thin, what is stiff. Ghilẓa — thickness. The Qurʾān uses the word in its concrete sense too: "a thick chain", "hard-hearted" (ghalīẓa'l-qalb at Āl ʿImrān 3/159).

The construction occurs in three places in the Qurʾān:

That these three stand side by side is worth recording. As was recorded at al-Ṭalāq, marriage is one of three things the Qurʾān describes as a "thick word" — and the other two are prophethood and a collective covenant.

Describing a word as "thick" does this in the language: it makes the word measurable like an object. A thin word snaps easily; a thick word does not. That is, the verse depicts bindingness not as a matter of ethics but as a matter of material.

The verse first uses a general expression (mina'l-nabiyyīn — from the prophets), then names five: you, Noah, Abraham, Moses, Jesus.

There are two points of word order:

One. The one addressed is named not in historical order but at the very head. Wa minka — "and from you" — comes before Noah, although Noah is named at the beginning of the chain of prophethood (as was recorded at Nūḥ). That is, the order is not chronological but rhetorical. The one being spoken to has been brought forward.

Two. This group of five recurs in the Qurʾān. The same five names occur together at al-Shūrā 42/13 as well — there it is said "He has laid down for you of religion what He enjoined upon Noah, and what We have revealed to you, and what We enjoined upon Abraham, Moses and Jesus". In both verses the same five names, in the same frame. It is common in the exegetical tradition to call this group ulu'l-ʿazm; the extent and the ground of the term are disputed, and no ruling is issued here.

And one further note: Jesus is named here too by the Qurʾān's invariable designation — ibn Maryam, "son of Mary". That the Qurʾān always ascribes him to his mother takes on a particular weight when it is read together with the fact that this comes immediately after the discussion of lineage in the fourth and fifth verses. Lineage is not something the Qurʾān passes over undiscussed in anyone's case.

This sentence is the most striking place in the verse, and it is usually passed over quickly.

The sentence says: a pledge has been taken — so that the truthful may be asked about their truthfulness.

صِدْق — root ص-د-ق. Truthfulness; and the concrete side of the root is firmness: rumḥun ṣadq — a firm spear. From the same root ṣadaqa, ṣadāq (the bridal gift), taṣdīq, ṣiddīq.

Note: the one who is asked is the ṣādiq. The verse does not say "so that He may ask the liars about their lies". Those to whom the questioning is addressed are the truthful.

This is a reversal worth recording. The expected sequence was: a pledge was taken so that those who do not keep it may render account. Instead the verse says that it is those who keep it who are asked.

Several explanations are transmitted for this expression in classical exegesis:

I record the third explanation particularly, because the word order of the verse supports it: in the sentence ṣādiqīn and ṣidqihim occur twice from the same root. That is, the question is framed not as "were you truthful?" but as "what became of your truthfulness?" Truthfulness is set down not as an adjective but as a work for which an account is rendered.

I record this reading as my own reading; its ground is the twofold repetition of the root.

"And He has prepared for the disbelievers a painful punishment."

The verse ends at two poles: on one side the truthfulness asked of the truthful, on the other the recompense prepared for those who cover. And this twofold structure is the herald of the siege section: from the ninth verse the same two sides will come on stage — those who keep their pledge (23) and those who cover (25).

The weight of a word depends not on who gives it but on what it is given to.

The verse says that what makes a word "thick" is one of the parties. Put into today's language: the bindingness of an undertaking comes less from the intention of the one who gives it than from to whom the undertaking is given.

And the second measure is more concrete: truthfulness is itself something for which an account will be asked. The matter does not end when a person counts himself "honest"; the verse says that the honest too will be questioned. An attribute is not an excuse.
