Key Verses

1. 29:41Al-Ankabut
   مَثَلُ ٱلَّذِينَ ٱتَّخَذُواْ مِن دُونِ ٱللَّهِ أَوۡلِيَآءَ كَمَثَلِ ٱلۡعَنكَبُوتِ ٱتَّخَذَتۡ بَيۡتٗاۖ وَإِنَّ أَوۡهَنَ ٱلۡبُيُوتِ لَبَيۡتُ ٱلۡعَنكَبُوتِۚ لَوۡ كَانُواْ يَعۡلَمُونَ
   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.
   In context

   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.
