Sahih al-Bukhari 465
Narrated Anas bin Malik:
Two of the companions of the Prophet (ﷺ) departed from him on a dark night and were led by two lights 
like lamps (going in front of them from Allah as a miracle) lighting the way in front of them, and 
when they parted, each of them was accompanied by one of these lights till he reached their 
(respective) houses.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، قَالَ حَدَّثَنَا أَنَسٌ، أَنَّ رَجُلَيْنِ، مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم خَرَجَا مِنْ عِنْدِ النَّبِيِّ صلى الله عليه وسلم فِي لَيْلَةٍ مُظْلِمَةٍ، وَمَعَهُمَا مِثْلُ الْمِصْبَاحَيْنِ يُضِيآنِ بَيْنَ أَيْدِيهِمَا، فَلَمَّا افْتَرَقَا صَارَ مَعَ كُلِّ وَاحِدٍ مِنْهُمَا وَاحِدٌ حَتَّى أَتَى أَهْلَهُ‏.‏
