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."  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ؓ يَقُولُ صَبَّحَ رَسُولُ اللَّهِ ﷺ خَيْبَرَ بُكْرَةً وَقَدْ خَرَجُوا بِالْمَسَاحِي فَلَمَّا رَأَوْهُ قَالُوا مُحَمَّدٌ وَالْخَمِيسُ وَأَحَالُوا إِلَى الْحِصْنِ يَسْعَوْنَ فَرَفَعَ النَّبِيُّ ﷺ يَدَيْهِ وَقَالَ اللَّهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ  

The Prophet ﷺ set out for Khaibar and reached it at night. He used not to attack if he reached the people at night, till the day broke. So, when the day dawned, the Jews came out with their bags and spades. When they saw the Prophet; they said, "Muhammad and his army!" The Prophet ﷺ said, Allahu--Akbar! (Allah is Greater) and Khaibar is ruined, for whenever we approach a nation (i.e. enemy to fight) then it will be a miserable morning for those who have been warned."  

أَنَّ النَّبِيَّ ﷺ خَرَجَ إِلَى خَيْبَرَ فَجَاءَهَا لَيْلاً وَكَانَ إِذَا جَاءَ قَوْمًا بِلَيْلٍ لاَ يُغِيرُ عَلَيْهِمْ حَتَّى يُصْبِحَ فَلَمَّا أَصْبَحَ خَرَجَتْ يَهُودُ بِمَسَاحِيهِمْ وَمَكَاتِلِهِمْ فَلَمَّا رَأَوْهُ قَالُوا مُحَمَّدٌ وَاللَّهِ مُحَمَّدٌ وَالْخَمِيسُ فَقَالَ النَّبِيُّ ﷺ اللَّهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ  

Messenger of Allah ﷺ reached Khaibar at night and it was his habit that, whenever he reached the enemy at night, he will not attack them till it was morning. When it was morning, the Jews came out with their spades and baskets, and when they saw him(i.e. the Prophet ﷺ ), they said, "Muhammad! By Allah! Muhammad and his army!" The Prophet ﷺ said, "Khaibar is destroyed, for whenever we approach a (hostile) nation (to fight), then evil will be the morning for those who have been warned."  

أَنَّ رَسُولَ اللَّهِ ﷺ 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 ﷺ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ  

"When the Messenger of Allah ﷺ set out for Khaibar, he approached it at night and when he came to a people during the night, he would not attack them until morning. So when the morning came, the Jews came out with their shovels and baskets, then when they saw him, they said: 'Muhammad! By Allah Muhammad has come with the Khamis (an army).' So the Messenger of Allah ﷺ said: 'Allahu Akbar! Khaibar is destroyed, for whenever we approach the land of people - then what an evil morning for those who have been warned.'"  

أَنَّ رَسُولَ اللَّهِ ﷺ حِينَ خَرَجَ إِلَى خَيْبَرَ أَتَاهَا لَيْلاً وَكَانَ إِذَا جَاءَ قَوْمًا بِلَيْلٍ لَمْ يُغِرْ عَلَيْهِمْ حَتَّى يُصْبِحَ فَلَمَّا أَصْبَحَ خَرَجَتْ يَهُودُ بِمَسَاحِيهِمْ وَمَكَاتِلِهِمْ فَلَمَّا رَأَوْهُ قَالُوا مُحَمَّدٌ وَافَقَ وَاللَّهِ مُحَمَّدٌ الْخَمِيسَ فَقَالَ رَسُولُ اللَّهِ ﷺ اللَّهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ  

Yahya related to me from Malik from Humayd at-Tawil from Anas ibn Malik that when the Messenger of Allah ﷺ went out to Khaybar, he arrived there at night, and when he came upon a people by night, he did not attack until morning. In the morning, the jews came out with their spades and baskets. When they saw him, they said, "Muhammad! By Allah, Muhammad and his army!" The Messenger of Allah ﷺ said "Allah is greater! Khaybar is destroyed. When we come to a people, it is an evil morning for those who have been warned . "  

أَنَّ رَسُولَ اللَّهِ ﷺ حِينَ خَرَجَ إِلَى خَيْبَرَ أَتَاهَا لَيْلاً وَكَانَ إِذَا أَتَى قَوْمًا بِلَيْلٍ لَمْ يُغِرْ حَتَّى يُصْبِحَ فَخَرَجَتْ يَهُودُ بِمَسَاحِيهِمْ وَمَكَاتِلِهِمْ فَلَمَّا رَأَوْهُ قَالُوا مُحَمَّدٌ وَاللَّهِ مُحَمَّدٌ وَالْخَمِيسُ فَقَالَ رَسُولُ اللَّهِ ﷺ اللَّهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ  

[Machine] I heard Anas ibn Malik saying, "The Messenger of Allah ﷺ attacked Khaybar in the morning, while they had already gone out for their work in the fields. When they saw the Messenger of Allah ﷺ, they said, 'Muhammad and the group have come.' The Messenger of Allah ﷺ raised his hands and said, 'Allahu Akbar (Allah is the Greatest)! Khaybar is destroyed. Whenever we descend upon a nation's territory, then the morning of those who are warned will be severe.'"  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ صَبَّحَ رَسُولُ اللهِ ﷺ خَيْبَرَ بُكْرَةً وَقَدْ خَرَجُوا بِالْمَسَاحِي فَلَمَّا نَظَرُوا إِلَى رَسُولِ اللهِ ﷺ قَالُوا مُحَمَّدٌ وَالْخَمِيسُ فَرَفَعَ رَسُولُ اللهِ ﷺ يَدَيْهِ وَقَالَ اللهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ  

[Machine] "The fighting intensified on the day of Khaybar, and I was among the ranks of Abu Talhah. The Messenger of Allah ﷺ said, 'Allahu Akbar! Khaybar is destroyed. Whenever we descend upon a people's territory, it is a morning of distress for the warned.'"  

اشْتَدَّ الْقِتَالُ يَوْمَ خَيْبَرَ فَكُنْتُ رَدِيفَ أَبِي طَلْحَةَ فَقَالَ رَسُولُ اللَّهِ ﷺ «اللَّهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ»  

"When the Messenger of Allah ﷺ set out for Khaibar, he approached it at night and when he came to a people during the night, he would not attack them until morning. So when the morning came, the Jews came out with their shovels and baskets, then when they saw him, they said: 'Muhammad! By Allah Muhammad has come with the Khamis (an army).' So the Messenger of Allah ﷺ said: 'Allahu Akbar! Khaibar is destroyed, for whenever we approach the land of people - then what an evil morning for those who have been warned.'" (Using translation from Tirmidhī 1550)   

أَنَّ رَسُولَ اللَّهِ ﷺ خَرَجَ إِلَى خَيْبَرَ لَيْلًا وَكَانَ إِذَا جَاءَ قَوْمًا بِلَيْلٍ لَمْ يُغِرْ حَتَّى يُصْبِحَ قَالَ فَلَمَّا أَصْبَحَ خَرَجَتْ يَهُودُ بِمَسَاحِيهَا وَمَكَاتِلِهَا فَلَمَّا رَأَوْهُ قَالُوا مُحَمَّدٌ وَالْخَمِيسُ فَقَالَ رَسُولُ اللَّهِ ﷺ «اللَّهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ»

(Using translation from Bukhārī 2945)

[Machine] The Messenger of Allah, ﷺ , arrived in Khaibar in the morning, while they were preparing for battle. When they saw the Messenger of Allah, ﷺ , they hurried towards the fortress, saying, "Muhammad and the army arrived." The Messenger of Allah, ﷺ , raised his hands and exclaimed, "Allahu Akbar" (Allah is the greatest) three times. Khaibar is destroyed! When we descend upon a people's land, it is a bad morning for those who have been warned.  

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
