S12
The spider's house
29:41 compares relying on anything other than God to "the home of the spider" — and calls it "the weakest of homes".
مَثَلُ ٱلَّذِينَ ٱتَّخَذُوا۟ مِن دُونِ ٱللَّهِ أَوْلِيَآءَ كَمَثَلِ ٱلْعَنكَبُوتِ ٱتَّخَذَتْ بَيْتًا ۖ وَإِنَّ أَوْهَنَ ٱلْبُيُوتِ لَبَيْتُ ٱلْعَنكَبُوتِ ۖ لَوْ كَانُوا۟ يَعْلَمُونَ٤١
Transliteration: mathalu alladhīna ittakhadhū min dūni l-lahi awliyāa kamathali l-ʿankabūti ittakhadhat baytan wa-inna awhana l-buyūti labaytu l-ʿankabūti law kānū yaʿlamūna
The example of those who take allies other than Allah is like that of the spider who takes a home. And indeed, the weakest of homes is the home of the spider, if they only knew.
Translation: Saheeh International
Key words
Awliyāʾ: allies, protectors. Ittakhadhat baytan: "takes a home"; the verb is grammatically feminine. Awhan al-buyūt: "the weakest of homes".
What the verse is about
It is a parable (mathal): not a statement about spiders, but about people who rely on false protectors.
Classical tafsir
Ibn Kathir. The idolaters "were like the house of a spider, which is so weak and frail". He also writes: like "a person who holds on to a spider's web, who does not gain any benefit from that".
Al-Jalālayn. The spider's home "neither protects it from heat nor cold".
Where they agree. Both read the weakness as practical: the web gives no shelter. Ibn Kathir stresses the uselessness of holding on to it; al-Jalālayn names what it fails to keep out. Neither discusses which sex of spider builds webs, or spider family life.
How it works
- The silk is strong. Established The silk of Darwin's bark spider (Caerostris darwini, Madagascar) is the toughest biological material measured: "The toughness of forcibly silked fibers averages 350 MJ/m3, with some samples reaching 520 MJ/m3", "more than twice tougher than any previously described silk" and over ten times tougher than Kevlar (Agnarsson, Kuntner & Blackledge 2010). Its webs cover up to 2.8 m², anchored by threads up to 25 m long across rivers.
- The home is weak. Established A web is a thin net, built to catch prey. It does not keep out wind, rain, heat, cold or predators. (This is ordinary observation; no named source on web function was read.)
- So both are true. The material is extraordinary; the shelter is not. That is exactly the gap the parable uses.
Points of awe
Reflection
Spider silk is, strand for strand, one of the toughest materials known. And yet the verse says: "the weakest of homes is the home of the spider, if they only knew" (29:41). Both are true. The point is not that the silk is weak. It is that something cleverly made can still give no real shelter.
Al-Jalālayn names what the web cannot do: it "neither protects it from heat nor cold". Ibn Kathir names the people the parable is about: those who rely on protectors other than God are like someone holding on to a spider's web.
The parable is not only about idols of stone. Anything we lean on in God's place can become a spider's house: money, status, a person, our own cleverness. These things may be impressive, even beautiful. They may hold for a while. But when the storm comes — illness, loss, death — they do not hold us up.
The verse ends with a quiet regret: "if they only knew". It is not mockery. It is an invitation to check what we are leaning on before we need it to hold.
Questions readers ask next
If spider silk is so strong, why is the spider's house the weakest?
Because a web is a trap, not a shelter: it keeps out neither heat nor cold (al-Jalālayn). Strength of material is not strength of refuge.
Is the verse about female spiders?
The verb is grammatically feminine, but that follows the noun's grammatical gender; the commentators read here do not draw a biological point from it.
Who are "those who take allies other than Allah"?
In context, those who worshipped idols; Ibn Kathir reads the verse about them. The lesson extends to anything relied on in God's place.
What does awhan mean?
"Weakest", the superlative of weak.
