There is no injustice greater, no crime worse than ignoring the signs of Allah after being reminded of them. This crime demonstrates the height of ingratitude, and is akin to carelessly discarding a sincere gift from someone who loves you. In fact, it’s even worse. This gift, guidance from Allah, is essential to our well being, so ignoring it is not only ungrateful, but foolish.
In Surah Kahf Allah addresses the horrifying result of those who commit this crime:
وَمَنْ أَظْلَمُ مِمَّنْ ذُكِّرَ بِآيَاتِ رَبِّهِ فَأَعْرَضَ عَنْهَا وَنَسِيَ مَا قَدَّمَتْ يَدَاهُ ۚ إِنَّا جَعَلْنَا عَلَىٰ قُلُوبِهِمْ أَكِنَّةً أَنْ يَفْقَهُوهُ وَفِي آذَانِهِمْ وَقْرًا ۖ وَإِنْ تَدْعُهُمْ إِلَى الْهُدَىٰ فَلَنْ يَهْتَدُوا إِذًا أَبَدًا
And who is more wrong than one who is reminded of the Signs of his Lord but turns away from them forgetting the deeds which his hands have sent forth? Verily We have set veils over their hearts lest they should understand this and over their ears a deafness. If you call them to guidance even then will they never accept it.
Since these people ignored guidance when it was given to them, Allah takes away their capacity to be guided in the future. Even if the Prophet SAWS himself, the best of callers, were to try and help them, they would never be guided.
The word أَكِنَّةً is used in the ayah to illustrate the inaccessibility of their hearts to guidance. Interestingly, أَكِنَّةً is also used to describe an eagle’s nest that is high up in the mountains beyond the reach of anyone, a place totally inaccessible. Imagining a heart that closed off should frighten any believer.
It is possible that these people might hear, or even understand guidance, but it will never truly penetrate their hearts, and they won’t be profoundly moved by it, deeming them spiritually decapacitated, paralyzed, and doomed.
Further, Allah says he places a وَقْرًا in their ears, which can be translate as a deafening object, but is more specifically used to describe the phenomenon of ears popping when climbing high. Continuing the imagery of a tall, unreachable mountain, the wording suggests that these people will hear things ,but won’t be able to comprehend or understand them clearly. They will stumble along lost, many times not even realizing it, as they assure themselves of their own righteousness.
What’s more is that the two senses, or faculties, which Allah blocks are the heart and the ears, both essential to guidance. The ear receives the speech of Allah, and the heart accepts and acts on it. With these senses blocked, these people are essentially left wandering blindly in a valley of wolves. Time is the only thing between them and eternal doom, and this is because when Allah graciously gave them guidance they recognized it, accepted it, but then justified turning away from it.
May Allah protect us. Ameen.
