The Quran references the spider building its web in a way that aligns with a key biological fact: female spiders are the ones that construct webs. Skeptics once argued that both male and female spiders build webs, but modern science confirms that web-building is predominantly a female activity.

Adult male spiders do not construct webs. Instead, they use their silk primarily for mating purposes, such as creating sperm webs. Females, on the other hand, build the intricate webs used for catching prey. This is well-documented in arachnology and has only been widely accepted in recent years. - Female Spiders Build Webs: Studies confirm that adult female spiders are the ones responsible for constructing webs, which are used for catching food and other survival functions. Male spiders may weave simple structures for mating purposes, but they do not build the typical webs associated with spiders. - Webs Require Constant Rebuilding: Spider webs are often damaged by environmental factors such as wind, rain, and dust. Each time a web catches prey, it sustains damage, requiring the spider to rebuild it regularly—sometimes nightly, using around 20 meters of silk.

The Quran in Surah Al-Ankabut (29:41) states:

In Arabic, the verb "It-takhathat اتَّخَذَتْ" is used, which is grammatically feminine, indicating that the spider building the web is female. This precise choice reflects modern biological knowledge about spiders.

The Quran’s description of the spider and its web, specifying that the builder is female, aligns with recent scientific discoveries. Additionally, the fragile and temporary nature of spider webs is aptly described. How could an illiterate man 1400 years ago have known that webs are built by females? This remarkable accuracy challenges assumptions about the source of this knowledge.
