The similitude of those who have taken protectors instead of Allah is like the similitude of the spider that has taken a house. And the weakest of houses is the spider’s house, if they knew.

Bayt al-'ankabut بَيْتُ الْعَنْكَبُوتِ 'spider's house' is an Arabic expression for a spider's web or cobweb. Now, a spider doesn't 'take' a house as though it came across a web and occupied it. It's not a house for the spider. Some spiders have burrows. Not all spiders spin webs. Regarding the strength of spider silk:

Properties -strength A dragline silk's tensile strength is comparable to that of high-grade alloy steel (450−2000 MPa), and about half as strong as aramid filaments, such as Twaron or Kevlar (3000 MPa). -density Consisting of mainly protein, silks are about a sixth of the density of steel (1.3 g/cm3 ). As a result, a strand long enough to circle the Earth would weigh less than 500 grams (18 oz). (Spider dragline silk has a tensile strength of roughly 1.3 GPa. The tensile strength listed for steel might be slightly higher—e.g. 1.65 GPa, but spider silk is a much less dense material, so that a given weight of spider silk is five times as strong as the same weight of steel.)

In another article we read:

Andy Davis, assistant research scientist in the Odum School of Ecology, spoke with National Geographic about Joro spider webs, seemingly strong enough to hold a bird.

“This is incredibly unusual,” said Davis. “To the best of our knowledge, this is a scientific first.”

When helping his son with his science project, Davis attempted to measure the strength of Joro spider webs, a species on which Davis is an expert. He measured that the webs could hold up to 69 grams, easily strong enough to support a common bird like the cardinal.

“Four or five months later, this guy calls me and says he’s found a bird sitting on a web,” said Davis. “And then I kind of put two and two together and realized that I had data that basically showed the same thing.”

Joro spiders have made a major impact along the east coast after hitching a ride from Asia. While not harmful, their population has exploded in a new habitat. Their webs now offer a valuable food source to birds, and even other spiders.

“These little spiders, [dewdrop spiders], kind of make their living hanging out on other spider’s webs and stealing their food,” said Davis. “In all the Joro webs I’ve seen this fall, I’ve probably seen these dewdrop spiders on at least 30 percent of them. So, the dewdrops are benefitting big time from the Joros.” Ecologist finds spider webs strong enough to hold birds - UGA Today

In another article we read of a spider's web that can catch birds.

Golden Orb Spiders, also known as Nephila, are one of the most fascinating creatures found in South Africa. With their striking colors and unique web-spinning abilities, these spiders are a wonder of nature. These spiders spin webs across game paths and roads to increase their chances of catching a meal.

One of the most amazing things about these spiders is the strength of their webs. The silk they produce is incredibly strong and flexible, able to withstand the wind and rain. This makes their webs perfect for catching prey, which includes insects, birds, and even small mammals. Yes, birds and mammals!

Olifants West Game Reserve is a great place to start your search, where you may witness incredible sights like Brass Brasset’s discovery of a blue waxbill caught in a Golden Orb Spider web. These birds are often caught in the spider’s webs while flying, but sometimes they are able to escape. Bird Caught Mid-Flight in Spider's Web

'Allah' didn't know how strong the 'spider's house' can be.
