Anas bin Malik said, "Whenever the Prophet ﷺ went out with us to fight (in Allah's cause) against any nation, he never allowed us to attack till morning and he would wait and see: if he heard Adhan he would postpone the attack and if he did not hear Adhan he would attack them." Anas added, "We reached Khaibar at night and in the morning when he did not hear the Adhan for the prayer, he (the Prophet ) rode and I rode behind Abi Talha and my foot was touching that of the Prophet. The inhabitants of Khaibar came out with their baskets and spades and when they saw the Prophet ﷺ they shouted 'Muhammad! By Allah, Muhammad and his army.' When Messenger of Allah ﷺ saw them, he said, "Allahu-Akbar! Allahu-Akbar! Khaibar is ruined. Whenever we approach a (hostile) nation (to fight), then evil will be the morning of those who have been warned."  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا غَزَا بِنَا قَوْمًا لَمْ يَكُنْ يَغْزُو بِنَا حَتَّى يُصْبِحَ وَيَنْظُرَ فَإِنْ سَمِعَ أَذَانًا كَفَّ عَنْهُمْ وَإِنْ لَمْ يَسْمَعْ أَذَانًا أَغَارَ عَلَيْهِمْ قَالَ فَخَرَجْنَا إِلَى خَيْبَرَ فَانْتَهَيْنَا إِلَيْهِمْ لَيْلاً فَلَمَّا أَصْبَحَ وَلَمْ يَسْمَعْ أَذَانًا رَكِبَ وَرَكِبْتُ خَلْفَ أَبِي طَلْحَةَ وَإِنَّ قَدَمِي لَتَمَسُّ قَدَمَ النَّبِيِّ ﷺ قَالَ فَخَرَجُوا إِلَيْنَا بِمَكَاتِلِهِمْ وَمَسَاحِيهِمْ فَلَمَّا رَأَوُا النَّبِيَّ ﷺ قَالُوا مُحَمَّدٌ وَاللَّهِ مُحَمَّدٌ وَالْخَمِيسُ قَالَ فَلَمَّا رَآهُمْ رَسُولُ اللَّهِ ﷺ قَالَ اللَّهُ أَكْبَرُ 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  

"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] Abu Talhah stood beside the Messenger of Allah ﷺ and said, "I see that my feet are touching the feet of the Messenger of Allah ﷺ ." The Messenger of Allah ﷺ gave them time until the people of agriculture went to their crops and the people of livestock went to their livestock. Then he raised his voice in takbeer (saying Allahu Akbar), and then he became angry with them. He said, "Indeed, when We descend upon a people's land, wretched is the morning of those who were warned." [Surah As-Saffat 37:177]  

وَأَبُو طَلْحَةَ إِلَى جَنْبِ رَسُولِ اللهِ ﷺ قَالَ وَإِنِّي لَأَرَى قَدَمِي لَتَمَسُّ قَدَمَ رَسُولِ اللهِ ﷺ قَالَ فَأَمْهَلَهُمْ رَسُولُ اللهِ ﷺ حَتَّى خَرَجَ أَهْلُ الزَّرْعِ إِلَى زُرُوعِهِمْ وَأَهْلُ الْمَوَاشِي إِلَى مَوَاشِيهِمْ قَالَكَبَّرَ ثُمَّ أَغَارَ عَلَيْهِمْ ثُمَّ قَالَ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ {فَسَاءَ صَبَاحُ الْمُنْذَرِينَ} [الصافات 177]  

[Machine] The Messenger of Allah ﷺ traveled to Khaibar and arrived there at night. He mentioned that whenever the Prophet ﷺ approached a place at night, the people there would not be disturbed until morning. If he heard the call to prayer, he would stop, but if the people were not praying, he would become angry with them. When morning came, he and the Muslims mounted their rides. The people of the village came out with their ropes and tools. When they saw the Messenger of Allah ﷺ and the Muslims, they said, "By Allah and Al-Khamis, this is Muhammad!" The Messenger of Allah ﷺ replied, "Allahu Akbar! Allahu Akbar! Khaibar is destroyed. Whenever we approach the land of a people, the morning is a bad time for those who are warned." Anas ibn Malik said, "I was by the side of Abu Talha, and indeed my foot touched the foot of the Messenger of Allah ﷺ .  

سَارَ رَسُولُ اللهِ ﷺ إِلَى خَيْبَرَ فَانْتَهَى إِلَيْهَا لَيْلًا قَالَ وَكَانَ رَسُولُ اللهِ ﷺ إِذَا طَرَقَ لَيْلًا لَمْ يُغِرْ عَلَيْهِمْ حَتَّى يُصْبِحَ فَإِنْ سَمِعَ أَذَانًا أَمْسَكَ وَإِنْ لَمْ يَكُونُوا يُصَلُّونَ أَغَارَ عَلَيْهِمْ قَالَ فَلَمَّا أَصْبَحْنَا رَكِبَ وَرَكِبَ الْمُسْلِمُونَ قَالَ فَخَرَجَ أَهْلُ الْقَرْيَةِ إِلَى حُرُوثِهِمْ مَعَهُمْ مَكَاتِلُهُمْ وَمَسَاحِيهِمْ فَلَمَّا رَأَوْا رَسُولَ اللهِ ﷺ وَالْمُسْلِمِينَ قَالُوا مُحَمَّدٌ وَاللهِ وَالْخَمِيسُ قَالَ فَقَالَ رَسُولُ اللهِ ﷺ اللهُ أَكْبَرُ اللهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ قَالَ أَنَسٌ وَإِنِّي لَرَدِيفُ أَبِي طَلْحَةَ وَإِنَّ قَدَمِي لَتَمَسُّ قَدَمَ رَسُولِ اللهِ ﷺ

[Machine] That the Messenger of Allah, ﷺ , when he attacked Khaybar, they had taken their water skins and ropes and had gone out to their fields in the morning. When they saw the Prophet of Allah, ﷺ , with his army, they turned and fled. The Messenger of Allah, ﷺ , said, "Allahu Akbar! Allahu Akbar! Allahu Akbar! Khaybar is ruined. When we descend upon a people's land, it is a bad morning for the warning ones."  

أَنَّ رَسُولَ اللهِ ﷺ لَمَّا صَبَّحَ خَيْبَرَ وَقَدْ أَخَذُوا مَسَاحِيَهُمْ وَمَكَاتِلَهُمْ وَغَدَوْا عَلَى حُرُوثِهِمْ فَلَمَّا رَأَوْا نَبِيَّ اللهِ ﷺ مَعَهُ الْخَمِيسُ نَكَصُوا مُدْبِرِينَ فَقَالَ رَسُولُ اللهِ ﷺ «اللهُ أَكْبَرُ اللهُ أَكْبَرُ اللهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ»
