al-Ṭalāq 65:10

Aʿadda'llāhu lahum ʿadhāban shadīdā, fa'ttaqu'llāha yā ūli'l-albābi'lladhīna āmanū, qad anzala'llāhu ilaykum dhikrā

"God has prepared a severe punishment for them. So guard yourselves against God, O you who possess the kernel and have believed. God has sent down to you a reminder."

Root ع د د (ʿ-d-d). From the same root-family as ʿidda and aḥṣū in the first verse of the sūra.

أَعَدَّ, in Form IV: to prepare. Its link with the root's sense of "counting" is direct — to prepare a thing is to count it up and complete it, to make it lack nothing. The distance English keeps between preparing and counting does not exist in Arabic.

And the root follows a path in the sūra:

At the beginning of the sūra a human being counts a period; at the end God has prepared a return. I record this as an observation; and I note as well that the word ʿadl comes from a separate root, so that no meaning may be drawn from the resemblance of sound.

لُبّ — root ل ب ب (l-b-b). And the concrete sense of this word is important: lubb is the core, the inside, the kernel of a thing. Not the shell of the walnut but its inside; the stone inside the flesh of the date.

In Arabic there are several words for the mind and each holds a different side:

• عَقْل (ʿaql) — its root is "to bind" (the camel's tether: ʿiqāl). The mind is what holds and reins in.
• فُؤَاد (fuʾād) — the heart; in its root there is "heat, kindling".
• لُبّ (lubb) — the kernel. The side of the mind that is not shell but core.

That is, ūlu'l-albāb are not "clever men"; they are those who grasp the kernel. Those who do not stay at the shell, who go down into the inside of the matter.

And the placing of the address here is striking.

Throughout the sūra the address had been yā ayyuha'l-nabiyy and second-person plural imperatives. Here, towards the end of the sūra, the one addressed is given a quality: those who grasp the kernel.

Why here? Because this verse is the place where the two parts are joined: on one side the rulings of the household, on the other the towns destroyed. To see the link between these two requires looking not at the shell but at the kernel. To draw a connection between a rule of maintenance and the collapse of a civilisation seems meaningless to one who stays on the surface.

I record this as my own reading.

ٱلَّذِينَ ءَامَنُوا۟ — "those who have believed". The adjective restricts ūlu'l-albāb. That is, the address is not to all who possess a mind, but to those of them who have believed.

This can be read as an exclusion; but it has a finer function. The verse sets belief and the possession of lubb side by side — and it enters the same family as the question recorded in al-Bayyina, of knowledge's remaining incomplete where it does not issue in a result. The mind that goes down to the kernel and belief are ascribed in the same sentence to the same person.

ذِكْر — root ذ ك ر (dh-k-r): to mention, to remember, to give voice to. This root was treated together with the differences of pattern in the sections al-Aʿlā and al-Ghāshiya; I do not repeat it.

Its coming indefinite — not al-dhikr but dhikran: "a reminder". The indeterminacy can be read here as magnification.

And this expression opens the next verse. What is dhikran? Verse 11 answers: رَّسُولًا — a messenger.
