al-Masad 111:5

Fī jīdihā ḥablun min masad "On her neck a rope of twisted fibre."

Arabic has more than one word for the neck, and the difference between them carries the whole verse here:

Jīd is the word preferred in Arabic poetry when a woman's beauty is being described; comparisons to the neck of a gazelle are built with this word. The word's field of association is ornament, elegance, the necklace.

And it occurs only here in the Qurʾān. A word occurring a single time, and in precisely this verse.

Now the work the verse does becomes plain.

The sentence could have used a neutral word for "on her neck" (ʿunuqihā). It does not. It chooses the word used for the neck on which jewels are hung — and onto that neck it puts not a necklace but a rope of twisted fibre.

The whole force of the expression comes from this substitution. The same place, the same word, an entirely different object. The place that is adorned becomes the place that is bound.

It is transmitted in the biographical sources that Umm Jamīl had a valuable necklace and said she would spend it in the cause of enmity to the Prophet. This report makes the verse more concrete still, but caution is required regarding its soundness; the meaning of the verse does not depend on this report — the association of the word jīd is already sufficient of itself.

Root ḥ-b-l: cord, rope, bond.

In the Qurʾān ḥabl mostly occurs as a bond to be held on to, a saving bond:

• "And hold fast, all together, to the rope of God" (Āl ʿImrān 3/103).
• "…unless with a rope from God and a rope from people" (Āl ʿImrān 3/112) — here ḥabl is in the sense of protection, guarantee.
• "We are nearer to him than his jugular vein" (Qāf 50/16) — ḥabl al-warīd.

The word's typical sense in the Qurʾān is the bond of rescue: what is held on to, what pulls one out, what protects. In this verse the rope occurs with the same word but its function has been reversed: not a rope held in the hand but a rope put around the neck.

Root m-s-d: to twist, to wind tightly, to strengthen fibres by winding them together.

The explanations transmitted regarding the word:

The core sense of the root is not the material but the process: being twisted. Twisting strengthens a rope; twisted fibre is many times stronger than straight fibre. That is, the word describes the rope's unbreakability.

The palm fibre explanation adds a social layer as well. Palm fibre was the cheapest, most ordinary material in Arabia, within everyone's reach; it was used for tethering animals and for tying loads. The wife of one of Mecca's wealthy families is described with the least valuable material of the period. An image that is the exact opposite of wealth.

Indefiniteness. Masad comes indefinite. Here too the indefiniteness can be read in the direction of tahwīl (making terrible): a bond whose kind is not fully known, not described.

The closings of the five verses: tabb — kasab — lahab — ḥaṭab — masad.

All end on short, closed syllables; four with the same -ab sound, the fifth with an -ad very close to it. The sounds b and t recur throughout the sūra. The result is a hard, striking rhythm — read aloud, it moves fast, clipped, and in the same tone all the way to the end.

This accords with the content; but I record it not as a claim of miracle but as an example of the sound character of the short Meccan sūras.
