[Machine] I heard Abdullah ibn Mas'ud say, "We accompanied the Messenger of Allah ﷺ during the time of Hudaybiyah. They mentioned that they camped on a sandy plain. The Messenger of Allah ﷺ said, 'Who will keep watch over us?' Bilal said, 'I will, O Messenger of Allah.' So they slept until the sun rose, and some of them woke up, including so-and-so and so-and-so, and among them was Umar. The Prophet ﷺ woke up and said, 'Do as you used to do.' So we did. He said, 'Do the same for those who are sleeping or forgetful.' The camel of the Messenger of Allah ﷺ excelled, so I went to look for it and found its rope hanging from a tree. I brought it, and he mounted it, and we set off. When revelation descended upon him, it intensified this experience for him, and we recognized this in him. He moved away from us, taking shelter behind us, and covered his head, and it intensified upon him until we knew that revelation had been sent down to him. Then he came to us and informed us that revelation had been sent down to him: 'Indeed, We have granted you a clear victory.'" [Quran 48:1]  

سَمِعْتُ عَبْدَ اللهِ بْنَ مَسْعُودٍ يَقُولُ أَقْبَلْنَا مَعَ رَسُولِ اللهِ ﷺ زَمَنَ الْحُدَيْبِيَةِ فَذَكَرُوا أَنَّهُمْ نَزَلُوا دَهَاسًا مِنَ الْأَرْضِ يَعْنِي بِالدَّهَاسِ الرَّمْلَ فَقَالَ رَسُولُ اللهِ ﷺ «مَنْ يَكْلَؤُنَا» فَقَالَ بِلَالٌ أَنَا يَا رَسُولَ اللهِ قَالَ «إِذًا تنَامُ فَنَامُوا حَتَّى طَلَعَتِ الشَّمْسُ فَاسْتَيْقَظَ نَاسٌ فِيهِمْ فُلَانٌ وَفُلَانٌ وَفِيهِمْ عُمَرُ فَاسْتَيْقَظَ النَّبِيُّ ﷺ» فَقَالَ «افْعَلُوا كَمَا كُنْتُمُ تَفْعَلُونَ» فَفَعَلْنَا قَالَ «كَذَلِكَ فَافْعَلُوا لِمَنْ نَامَ أَوْ نَسِيَ» قَالَ فَضَلَّتْ نَاقَةُ رَسُولِ اللهِ ﷺ فَطَلَبْتُهَا فَوَجَدْتُ حَبْلَهَا قَدْ تَعَلَّقَ بِشَجَرَةٍ فَجِئْتُ بِهَا فَرَكِبَ فَسِرْنَا وَكَانَ النَّبِيُّ ﷺ إِذَا نَزَلَ عَلَيْهِ الْوَحْيُ اشْتَدَّ ذَلِكَ عَلَيْهِ وَعَرَفْنَا ذَلِكَ فِيهِ فَتَنَحَّى مُنْتَبِذًا خَلْفَنَا فَجَعَلَ يُغَطِّي رَأْسَهُ فَيَشْتَدُّ عَلَيْهِ حَتَّى عَرَفْنَا أَنَّهُ قَدْ أُنْزِلَ عَلَيْهِ فَأَتَانَا فَأَخْبَرَنَا أَنَّهُ أُنْزِلَ عَلَيْهِ {إِنَّا فَتَحْنَا لَكَ فَتْحًا مُبِينًا} [الفتح 1]
