Sahih al-Bukhari 4197
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ حُمَيْدٍ الطَّوِيلِ، عَنْ أَنَسٍ ـ رضى الله عنه أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَتَى خَيْبَرَ لَيْلاً، وَكَانَ إِذَا أَتَى قَوْمًا بِلَيْلٍ لَمْ يُغِرْ بِهِمْ حَتَّى يُصْبِحَ، فَلَمَّا أَصْبَحَ خَرَجَتِ الْيَهُودُ بِمَسَاحِيهِمْ وَمَكَاتِلِهِمْ، فَلَمَّا رَأَوْهُ قَالُوا مُحَمَّدٌ وَاللَّهِ، مُحَمَّدٌ وَالْخَمِيسُ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم " خَرِبَتْ خَيْبَرُ، إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ ".
The Messenger of Allah came to Khaybar at night. Whenever he came upon a people at night, he did not attack them until morning. When morning came, the Jews went out with their picks and baskets. When they saw him, they said, “Muḥammad! By Allah, Muḥammad and the army!” The Prophet said, “Khaybar is ruined. When we descend upon the open ground of a people, evil is the morning of those who were warned.”
