"The Messenger of Allah said: 'There are those who recite the Qur'an but it does not go any deeper than their collarbones. They will pass through Islam like an arrow passing through its target.'" (Using translation from Ibn Mājah 171)
وَقَالَ رَسُولُ اللهِ ﷺ لَيَقْرَأَنَّ الْقُرْآنَ أَقْوَامٌ مِنْ أُمَّتِي يَمْرُقُونَ مِنَ الإِسْلامِ كَمَا يَمْرُقُ السَّهْمُ مِنَ الرَّمِيَّةِ
