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] The Messenger of Allah ﷺ headed towards Khaibar and we reached there at night. When we woke up in the morning, he mounted his ride and the Muslims mounted theirs. I rode behind Abu Talha and my feet touched the feet of the Messenger of Allah ﷺ . The people of Khaibar came out with their crops and goods. When they saw the Prophet ﷺ and the Muslims, they turned back hastily and said, "Muhammad and his army have come!" The Messenger of Allah ﷺ said, "Allah is the Greatest! Khaibar is destroyed. When we descend upon the people's land, it'll be an evil morning for those who were warned." (Surah As-Saffat 37:177)  

سَارَ رَسُولُ اللهِ ﷺ إِلَى خَيْبَرَ فَانْتَهَيْنَا إِلَيْهَا لَيْلًا فَلَمَّا أَصْبَحْنَا الْغَدَاةَ رَكِبَ وَرَكِبَ الْمُسْلِمُونَ وَرَكِبْتُخَلْفَ أَبِي طَلْحَةَ وَإِنَّ قَدَمِي لَتَمَسُّ قَدَمَ رَسُولِ اللهِ ﷺ وَخَرَجَ أَهْلُ خَيْبَرَ بِمَكَاتِلِهِمْ وَمَسَاحِيهِمْ إِلَى زُرُوعِهِمْ وَأَرْضِيهِمْ فَلَمَّا رَأَوُا النَّبِيَّ ﷺ وَالْمُسْلِمِينَ رَجَعُوا هِرَابًا وَقَالُوا مُحَمَّدٌ وَالْخَمِيسُ فَقَالَ رَسُولُ اللهِ ﷺ اللهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ {فَسَاءَ صَبَاحُ الْمُنْذَرِينَ} [الصافات 177]  

[Machine] "When the Prophet of Allah, ﷺ , set out towards Khaibar after they had gathered their forces and they went to their land and territory, and when they saw the Prophet of Allah, ﷺ , accompanied by the army, they turned back fleeing. And the Prophet of Allah, ﷺ , said, 'Allahu Akbar, Allahu Akbar! Indeed, when we descend upon the land of a people, then it is a bad morning for those who are warned.'"  

لَمَّا صَبَّحَ نَبِيُّ اللهِ ﷺ خَيْبَرَ وَقَدْ أَخَذُوا مَسَاحِيَهُمْ وَغَدَوْا إِلَى حُرُوثِهِمْ وَأَرْضِهِمْ فَلَمَّا رَأَوْا نَبِيَّ اللهِ ﷺ مَعَهُ الْجَيْشُ نَكَصُوا مُدْبِرِينَ فَقَالَ نَبِيُّ اللهِ اللهُ أَكْبَرُ اللهُ أَكْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ  

[Machine] The Prophet of Allah, ﷺ , arrived at Khaybar, and they had gathered their forces and set out early in the morning. When they saw the Prophet of Allah, ﷺ , with his army, they turned and fled. The Prophet of Allah, ﷺ , said, "Allahu Akbar (Allah is the Greatest), Allahu Akbar, Khaybar has been ruined. When we set foot in the territory of a people, it is a calamitous morning for those who have been warned."  

صَبَّحَ نَبِيُّ اللهِ ﷺ خَيْبَرَ وَقَدْ أَخَذُوا مَسَاحِيَهُمْ وَغَدَوْا إِلَى حُرُوثِهِمْ فَلَمَّا رَأَوْا نَبِيَّ اللهِ ﷺ مَعَهُ الْجَيْشُ نَكَصُوا مُدْبِرِينَ فَقَالَ نَبِيُّ اللهِ ﷺ اللهُ أَكْبَرُ اللهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ قَالَ  

[Machine] When the Messenger of Allah, ﷺ , set out for the battle of Khaybar and his companions had saddled their horses and prepared themselves, they began their journey towards their destination. As they saw the Prophet, ﷺ , with the army, they turned away in retreat. The Prophet, ﷺ , exclaimed, "Allahu Akbar! Allahu Akbar! When we descend upon a people's land, it is a dreadful morning for the warned."  

لَمَّا صَبَّحَ رَسُولُ اللهِ ﷺ خَيْبَرَ وَقَدْأَخَذُوا مَسَاحِيَهُمْ وَغَدَوْا إِلَى حُرُوثِهِمْ وَأَرْضِيهِمْ فَلَمَّا رَأَوْا النَّبِيَّ ﷺ مَعَهُ الْجَيْشُ نَكَصُوا مُدْبِرِينَ فَقَالَ نَبِيُّ اللهِ ﷺ اللهُ أَكْبَرُ اللهُ أَكْبَرُ 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

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)   

أَنَّ رَسُولَ اللهِ ﷺ خَرَجَ إِلَى خَيْبَرَ فَجَاءَنَا لَيْلًا وَكَانَ إِذَا جَاءَ قَوْمًا بِاللَّيْلِ لَا يُغِيرُ عَلَيْهِمْ حَتَّى يُصْبِحَ فَلَمَّا أَصْبَحَ خَرَجَتْ يَهُودُ بِمَسَاحِيهِمْ وَمَكَاتِلِهِمْ فَلَمَّا رَأَوْهُ قَالُوا مُحَمَّدٌ وَاللهِ مُحَمَّدٌ وَالْخَمِيسُ فَقَالَ النَّبِيُّ ﷺ اللهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ {فَسَاءَ صَبَاحُ الْمُنْذَرِينَ} [الصافات 177]  

"لَمَّا صَبَّحَ النَّبِىُّ ﷺ خَيْبَرَ وَقَدْ أَخَذُوا مِسَاحَهُمْ (*) وَمَكَاتِلَهُمْ (*)

وَغَدَوْا عَلَى حُرُوثِهِمْ (* *) فَلَمَّا رَأَوا النَّبِىَّ ﷺ مَعَهُ الْجَيْشُ نَكَصُوا مُدْبِرِينَ. فَقَالَ رَسُولُ الله ﷺ : الله أَكْبَرُ الله أَكْبَرُ خَرِبَتْ خَيْبَرُ، إِنَّمَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ".
