We reached Khaibar early in the morning and the inhabitants of Khaibar came out carrying their spades, and when they saw the Prophet ﷺ they said, "Muhammad! By Allah! Muhammad and his army!" The Prophet ﷺ said, "Allahu-Akbar! Khaibar is destroyed, for whenever we approach a (hostile) nation (to fight) then evil will be the morning for those who have been warned." We then got the meat of donkeys (and intended to eat it), but an announcement was made by the announcer of the Prophet, "Allah and His Apostle forbid you to eat the meat of donkeys as it is an impure thing."

Messenger of Allah 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."

The Prophet ﷺ reached Khaibar in the morning, while the people were coming out carrying their spades over their shoulders. When they saw him they said, "This is Muhammad and his army! Muhammad and his army!" So, they took refuge in the fort. The Prophet ﷺ raised both his hands and said, "Allahu Akbar, Khaibar is ruined, for when we approach a nation (i.e. enemy to fight) then miserable is the morning of the warned ones." Then we found some donkeys which we (killed and) cooked: The announcer of the Prophet ﷺ announced: "Allah and His Apostle forbid you to eat donkey's meat." So, all the pots including their contents were turned upside down.

Then they began to advance towards the fortress. The Messenger of Allah ﷺ raised his hands and then said Allahu Akbar three times. He said, "Khaibar is destroyed. When we descend upon a nation's territory, it is a misfortune for the warners (i.e., the enemies). Indeed, we have caused red camels to retreat from the village and we have fattened them. The Messenger of Allah ﷺ said, "Indeed, Allah and His Messenger forbid you from domestic red camels, for they are impure and from the work of Satan."

When we descend upon a people's land, it is a bad morning for those who have been warned.  

البيهقي:١٨٤٧٠أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ أَخْبَرَنِي أَبُو نَصْرٍ أَحْمَدُ بْنُ سَهْلٍ الْفَقِيهُ بِبُخَارَى أنبا صَالِحُ بْنُ مُحَمَّدٍ الْحَافِظُ ثنا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ أَبُو مَعْمَرٍ الْهُذَلِيُّ ثنا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ أَيُّوبَ عَنْ مُحَمَّدِ بْنِ سِيرِينَ عَنْ أَنَسِ بْنِ مَالِكٍ ؓ قَالَ

صَبَّحَ رَسُولُ اللهِ ﷺ خَيْبَرَ بُكْرَةً وَقَدْ خَرَجُوا بِالْمَسَاحِي فَلَمَّا نَظَرُوا إِلَى رَسُولِ اللهِ ﷺ جَاءُوا يَسْعَوْنَ إِلَى الْحِصْنِ وَقَالُوا مُحَمَّدٌ وَالْخَمِيسُ فَرَفَعَ رَسُولُ اللهِ ﷺ يَدَيْهِ ثُمَّ قَالَ اللهُ أَكْبَرُ اللهُ أَكْبَرُ ثَلَاثَ مَرَّاتٍ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ  

رَوَاهُ الْبُخَارِيُّ فِي الصَّحِيحِ عَنْ عَبْدِ اللهِ بْنِ مُحَمَّدٍ وَغَيْرِهِ عَنْ سُفْيَانَ
