The Prophet ﷺ said in his narration of a dream that he saw, "He whose head was being crushed with a stone was one who learnt the Qur'an but never acted on it, and slept ignoring the compulsory prayers."
عَنِ النَّبِيِّ ﷺ فِي الرُّؤْيَا قَالَ أَمَّا الَّذِي يُثْلَغُ رَأْسُهُ بِالْحَجَرِ فَإِنَّهُ يَأْخُذُ الْقُرْآنَ فَيَرْفِضُهُ وَيَنَامُ عَنِ الصَّلاَةِ الْمَكْتُوبَةِ
