Sahih al-Bukhari 7030, 7031
Narrated Ibn `Umar:
I was a young unmarried man during the lifetime of the Prophet. I used to sleep in the mosque. 
Anyone who had a dream, would narrate it to the Prophet. I said, "O Allah! If there is any good for me 
with You, then show me a dream so that Allah's Messenger (ﷺ) may interpret it for me." So I slept and saw 
(in a dream) two angels came to me and took me along with them, and they met another angel who 
said to me, "Don't be afraid, you are a good man." They took me towards the Fire, and behold, it was 
built inside like a well, and therein I saw people some of whom I recognized, and then the angels took 
me to the right side. In the morning, I mentioned that dream to Hafsa. Hafsa told me that she had 
mentioned it to the Prophet (ﷺ) and he said, "`Abdullah is a righteous man if he only prays more at night." 
(Az-Zuhri said, "After that, `Abdullah used to pray more at night.")
حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا هِشَامُ بْنُ يُوسُفَ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ، قَالَ كُنْتُ غُلاَمًا شَابًّا عَزَبًا فِي عَهْدِ النَّبِيِّ صلى الله عليه وسلم وَكُنْتُ أَبِيتُ فِي الْمَسْجِدِ، وَكَانَ مَنْ رَأَى مَنَامًا قَصَّهُ عَلَى النَّبِيِّ صلى الله عليه وسلم فَقُلْتُ اللَّهُمَّ إِنْ كَانَ لِي عِنْدَكَ خَيْرٌ فَأَرِنِي مَنَامًا يُعَبِّرُهُ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم، فَنِمْتُ فَرَأَيْتُ مَلَكَيْنِ أَتَيَانِي فَانْطَلَقَا بِي، فَلَقِيَهُمَا مَلَكٌ آخَرُ فَقَالَ لِي لَنْ تُرَاعَ، إِنَّكَ رَجُلٌ صَالِحٌ، فَانْطَلَقَا بِي إِلَى النَّارِ، فَإِذَا هِيَ مَطْوِيَّةٌ كَطَىِّ الْبِئْرِ، وَإِذَا فِيهَا نَاسٌ قَدْ عَرَفْتُ بَعْضَهُمْ، فَأَخَذَا بِي ذَاتَ الْيَمِينِ، فَلَمَّا أَصْبَحْتُ ذَكَرْتُ ذَلِكَ لِحَفْصَةَ‏.‏ 
فَزَعَمَتْ حَفْصَةُ أَنَّهَا قَصَّتْهَا عَلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ ‏
"‏ إِنَّ عَبْدَ اللَّهِ رَجُلٌ صَالِحٌ لَوْ كَانَ يُكْثِرُ الصَّلاَةَ مِنَ اللَّيْلِ ‏"‏‏.‏ قَالَ الزُّهْرِيُّ وَكَانَ عَبْدُ اللَّهِ بَعْدَ ذَلِكَ يُكْثِرُ الصَّلاَةَ مِنَ اللَّيْلِ‏.‏
