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] 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] 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

كَانَ النَّبِيُّ ﷺ إِذَا غَزَا قَوْمًا لَمْ يَغْزُ حَتَّى يُصْبِحَ فَيَنْظُرَ فَإِنْ سَمِعَ أَذَانًا كَفَّ عَنْهُمْ وَإِنْ لَمْ يَسْمَعْ أَذَانًا أَغَارَ عَلَيْهِمْ قَالَ فَخَرَجْنَا إِلَى خَيْبَرَ فَانْتَهَيْنَا إِلَيْهِمْ لَيْلًا فَلَمَّا أَصْبَحَ وَلَمْ يَسْمَعْ أَذَانًا رَكِبَ رَسُولُ اللَّهِ ﷺ وَرَكِبْتُ خَلْفَ أَبِي طَلْحَةَ وَإِنَّ قَدَمَيَّ لَتَمَسُّ قَدَمَ رَسُولِ اللَّهِ ﷺ فَخَرَجُوا عَلَيْنَا بِمَكَاتِلِهِمْ وَمَسَاحِيهِمْ فَلَمَّا رَأَوَا النَّبِيَّ ﷺ قَالُوا مُحَمَّدٌ وَاللَّهِ مُحَمَّدٌ وَالْخَمِيسُ فَلَمَّا رَآهُمُ النَّبِيُّ ﷺ قَالَ «اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ»

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!
