The short answer
Quran 29:41 is a parable: those who take protectors other than Allah are like a spider that takes a house, and the frailest of houses is the spider's. The point is not the strength of the thread but the weakness of the house as a shelter, just as false objects of trust cannot protect anyone.
Allah says: "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" 1.
This is a parable, and tafsir explains it clearly. People hope their idols will benefit them or intercede for them, just as a spider builds a house hoping for protection from heat, cold and attack. But the spider's house "does not ward off any cold nor prevent any heat" 2. Likewise, anything relied on instead of Allah (an idol, money, status, people) looks like shelter and gives none when it matters.
A modest note that many readers enjoy: spider silk is famously strong for its weight. The verse does not deny that. It speaks of the house (bayt), and as a home a web is open to wind, rain and a single sweep of the hand. The verse also uses a feminine verb for the spider building its home. Arabic treats ankabut (spider) as a feminine noun, so this is natural grammar, not a statement about biology. (In many web-building species young spiders of both sexes spin webs; it is mainly adult females that keep doing so, while adult males tend to wander.)
The next verses stress that these examples need thought: "none will understand them except those of knowledge" 3. The Quran uses other small creatures in the same way: all false gods together could not create a fly, or even recover what a fly snatches from them 4, and Allah is not shy to give the example of a mosquito 5. Tafsir notes that disbelievers mocked such examples while believers found guidance in them 6.
The lesson: build your life on trust in Allah, the only shelter that never gives way.
Those who take allies besides Allah are like a spider; its house is the weakest of houses.
مَثَلُ ٱلَّذِينَ ٱتَّخَذُواْ مِن دُونِ ٱللَّهِ أَوۡلِيَآءَ كَمَثَلِ ٱلۡعَنكَبُوتِ ٱتَّخَذَتۡ بَيۡتࣰ اۖ وَإِنَّ أَوۡهَنَ ٱلۡبُيُوتِ لَبَيۡتُ ٱلۡعَنكَبُوتِۚ لَوۡ كَانُواْ يَعۡلَمُونَ ٤١
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
The example of the idolaters who took idols whom they worshipped other than Allah in the hope that they will benefit them or intercede for them is like that of a spider that builds a house to protect it from heat and cold and from an assault against it. The frailest of all houses is the spider’s as it does not ward off any cold nor prevent any heat. Similarly, their idols will not benefit nor harm nor intercede. If the idolaters knew that, they would not have taken idols that they worship besides Allah.
None understand these examples except those of knowledge.
وَتِلۡكَ ٱلۡأَمۡثَٰلُ نَضۡرِبُهَا لِلنَّاسِۖ وَمَا يَعۡقِلُهَآ إِلَّا ٱلۡعَٰلِمُونَ ٤٣
And these examples We present to the people, but none will understand them except those of knowledge
False gods could never create a fly, nor recover what it takes from them.
يَٰٓأَيُّهَا ٱلنَّاسُ ضُرِبَ مَثَلࣱ فَٱسۡتَمِعُواْ لَهُۥٓۚ إِنَّ ٱلَّذِينَ تَدۡعُونَ مِن دُونِ ٱللَّهِ لَن يَخۡلُقُواْ ذُبَابࣰ ا وَلَوِ ٱجۡتَمَعُواْ لَهُۥۖ وَإِن يَسۡلُبۡهُمُ ٱلذُّبَابُ شَيۡـࣰٔ ا لَّا يَسۡتَنقِذُوهُ مِنۡهُۚ ضَعُفَ ٱلطَّالِبُ وَٱلۡمَطۡلُوبُ ٧٣
O people, an example is presented, so listen to it. Indeed, those you invoke besides Allah will never create [as much as] a fly, even if they gathered together for that purpose. And if the fly should steal away from them a [tiny] thing, they could not recover it from him. Weak are the pursuer and pursued
Allah is not shy to present the example of a mosquito or what is smaller.
۞إِنَّ ٱللَّهَ لَا يَسۡتَحۡيِۦٓ أَن يَضۡرِبَ مَثَلࣰ ا مَّا بَعُوضَةࣰ فَمَا فَوۡقَهَاۚ فَأَمَّا ٱلَّذِينَ ءَامَنُواْ فَيَعۡلَمُونَ أَنَّهُ ٱلۡحَقُّ مِن رَّبِّهِمۡۖ وَأَمَّا ٱلَّذِينَ كَفَرُواْ فَيَقُولُونَ مَاذَآ أَرَادَ ٱللَّهُ بِهَٰذَا مَثَلࣰ اۘ يُضِلُّ بِهِۦ كَثِيرࣰ ا وَيَهۡدِي بِهِۦ كَثِيرࣰ اۚ وَمَا يُضِلُّ بِهِۦٓ إِلَّا ٱلۡفَٰسِقِينَ ٢٦
Indeed, Allah is not timid to present an example - that of a mosquito or what is smaller than it. And those who have believed know that it is the truth from their Lord. But as for those who disbelieve, they say, "What did Allah intend by this as an example?" He misleads many thereby and guides many thereby. And He misleads not except the defiantly disobedient
Allah does not shy away from using whatever example He wishes, whether that be of a gnat or anything bigger than it. The believers know and trust that there is wisdom in the use of such examples, while the disbelievers will make fun, asking each other why Allah uses examples with lowly creatures, such as gnats, flies and spiders. Allah replies that in these examples lie guidance, direction and a test for people. There are many people who are misguided by Allah through these examples, because they refuse to consider them; and there are many who He guides along the right path because they learn from them. He does not misguide anyone except those who deserve to be misguided. They are those who do not obey Him.
