سورة البقرة

إِنَّ اللَّهَ لَا يَسْتَحْيِي أَنْ يَضْرِبَ مَثَلًا مَا بَعُوضَةً فَمَا فَوْقَهَا ۚ فَأَمَّا الَّذِينَ آمَنُوا فَيَعْلَمُونَ أَنَّهُ الْحَقُّ مِنْ رَبِّهِمْ ۖ وَأَمَّا الَّذِينَ كَفَرُوا فَيَقُولُونَ مَاذَا أَرَادَ اللَّهُ بِهَٰذَا مَثَلًا ۘ يُضِلُّ بِهِ كَثِيرًا وَيَهْدِي بِهِ كَثِيرًا ۚ وَمَا يُضِلُّ بِهِ إِلَّا الْفَاسِقِينَ ﴿٢٦

Surah al-Baqarah

26. Allah does not shy away from presenting a parable of a gnat, or something above it. As for those who believe, they know that it is the Truth from their Lord. But as for those who disbelieve, they say, “What did Allah mean by this parable?” He misleads many by it, and He guides many by it, but He misleads none but the wrongdoers.
