Wool

In its five mentions across the Quran, wool occupies two absolute extremes: it is the quiet, grounding comfort of a nomadic home in this world, and the terrifying metric of physical collapse on the Day of Judgment. The Quran does not document wool as an economic trade commodity or dwell on the mechanics of weaving. Instead, it places the raw material precisely at the center of temporary human shelter, before using its weightless, easily pulled fibers to describe the final destruction of the earth's heaviest geological structures.

A Material for Temporary Comfort

In the life of this world, wool is framed as a deliberate divine provision designed to insulate and ease physical burdens. Verse 16:80 details how God provides resting places through the skins of animals, creating portable homes that are deliberately "light [to handle] when you travel and when you set up camp." Along with fur and hair, wool is extracted from livestock to give humanity "furnishings and comfort for a while" (16:80).

The phrasing emphasizes both the immediate utility and the impermanence of these materials. Wool provides a tangible layer of security against harsh environments, yielding rugs, blankets, and tent fabrics that make the earth habitable. Yet the Quran attaches the condition "for a while" to this comfort, setting up a sharp contrast with how the material is invoked in descriptions of the Hereafter. What serves as a reliable, cushioning staple of domestic life today is repurposed in the text as a symbol of ultimate fragility.

Why are mountains compared to tufts of wool?

The remaining four verses mentioning wool abruptly shift the context to the cataclysm of the Last Day, using its physical properties to illustrate the total loss of the earth's structural integrity. In Surah Al-Ma'arij, the text warns of a Day when the sky will turn "like molten brass" and the mountains will become "like tufts of wool" (70:8-9). This precise geological collapse is echoed in Surah Al-Qari'ah, which places the image alongside mass human panic: "On a Day when people will be like scattered moths, and the mountains like tufts of wool" (101:4-5).

The imagery relies on how raw, unspun wool behaves. Once plucked or fluffed, it possesses no inherent solidity; its fibers pull apart under the slightest tension and drift helplessly in the air. By likening the towering, deeply rooted mountains to this textile, the Quran signals the total suspension of physical laws. Classical commentators expanded on the specific Arabic term 'ihn used in these verses. As al-Tha'labi notes (Tafsir al-Thalabi, 27/345), early scholars like Muqatil described it strictly as "fluffed wool." Al-Hasan al-Basri offered a more precise visual, specifying it as "red wool, which is the weakest of wool." He explained that the destruction of the earth's peaks happens in distinct stages of degradation: the mountains first shatter into pouring sand, then loosen into fluffed wool, and finally dissolve into scattered dust.

This progression serves as a stark reorientation of what humans consider permanent. The very material that provides warmth and weight inside a fragile tent in this life becomes the final state of the most imposing rock formations on earth. On a Day when the heavens melt into brass and populations scatter like moths, the mountains themselves are stripped of their stone foundations, leaving them suspended in the air like brightly dyed, weightless tufts of wool.
