2:26
إِنَّ اللَّهَ لاَ يَسْتَحْيِي أَنْ يَضْرِبَ مَثَلا ً مَا بَعُوضَة ً فَمَا فَوْقَهَا فَأَمَّا الَّذِينَ آمَنُوا فَيَعْلَمُونَ أَنَّهُ الْحَقُّ مِنْ رَبِّهِمْ وَأَمَّا الَّذِينَ كَفَرُوا فَيَقُولُونَ مَاذَا أَرَادَ اللَّهُ بِهَذَا مَثَلا ً يُضِلُّ بِه ِِ كَثِيرا ً وَيَهْدِي بِه ِِ كَثِيرا ً وَمَا يُضِلُّ بِهِ~ِ إِلاَّ الْفَاسِقِينَ

God does not shy away from putting forth the example of a mosquito, or anything above it. As for those who believe, they know that it is the truth from their Lord. As for the rejecters, they say: "What does God intend with this example?" He strays many by it, and He guides many by it; but He only strays by it the wicked.
