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  

"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  

[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  

"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".
