حَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُعَاذٌ، قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، حَدَّثَنَا أَنَسٌ ـ رضى الله عنه ـ 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.‏

Narrated Anas bin Malik

Allah's Messenger (ﷺ) reached Khaibar in the early morning and the people of Khaibar came out with their spades, and when they saw the Prophet (ﷺ) they said, "Muhammad and his army!" and returned hurriedly to take refuge in the fort. The Prophet (ﷺ) raised his hands and said, "Allah is Greater! Khaibar is ruined ! If we approach a nation, then miserable is the morning of those who are warned."
