Al-Ankabut - 29:41

مَثَلُ الَّذِينَ اتَّخَذُوا مِن دُونِ اللَّهِ أَوْلِيَاء كَمَثَلِ الْعَنكَبُوتِ اتَّخَذَتْ بَيْتًا وَإِنَّ أَوْهَنَ الْبُيُوتِ لَبَيْتُ الْعَنكَبُوتِ لَوْ كَانُوا يَعْلَمُونَ
[29:41]
The parable of those who take guardians besides Allah is as the parable of the spider that makes for itself a house; and most surely the frailest of the houses is the spider's house did they but know.
The parable of those who take protectors other than Allah is that of the spider, who builds (to itself) a house; but truly the flimsiest of houses is the spider's house;- if they but knew.
The likeness of those who choose other patrons than Allah is as the likeness of the spider when she taketh unto herself a house, and lo! the frailest of all houses is the spider's house, if they but knew.
