Narrated Samura bin Jundab:
حَدَّثَنَا مُؤَمَّلُ بْنُ هِشَامٍ ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ ، قَالَ حَدَّثَنَا عَوْفٌ ، قَالَ حَدَّثَنَا أَبُو رَجَاءٍ ، قَالَ حَدَّثَنَا سَمُرَةُ بْنُ جُنْدَبٍ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم فِي الرُّؤْيَا قَالَ " أَمَّا الَّذِي يُثْلَغُ رَأْسُهُ بِالْحَجَرِ فَإِنَّهُ يَأْخُذُ الْقُرْآنَ فَيَرْفِضُهُ وَيَنَامُ عَنِ الصَّلاَةِ الْمَكْتُوبَةِ " .
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."
