Ibn 'Umar said, "We were on a raid and the people fled. We said, 'How can we meet the Prophet, (ﷺ), when we have run away? It has been revealed, "unless he is withdrawing to rejoin the fight" (8:16)." We said, 'We will not go to Madina and then no one will see us.' Then we said, 'Perhaps we should go.' The Prophet, (ﷺ), came from the Fajr prayer and we said, 'We fled.' He said, 'You are those rejoining the fight."' We kissed his hand. He said, 'I am your group.*'"

حَدَّثَنَا مُوسَى، قَالَ‏:‏ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ يَزِيدَ بْنِ أَبِي زِيَادٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، عَنِ ابْنِ عُمَرَ قَالَ‏:‏ كُنَّا فِي غَزْوَةٍ، فَحَاصَ النَّاسُ حَيْصَةً، قُلْنَا‏:‏ كَيْفَ نَلْقَى النَّبِيَّ صلى الله عليه وسلم وَقَدْ فَرَرْنَا‏؟‏ فَنَزَلَتْ‏:‏ ‏{‏إِلاَّ مُتَحَرِّفًا لِقِتَالٍ‏}‏، فَقُلْنَا‏:‏ لاَ نَقْدِمُ الْمَدِينَةَ، فَلاَ يَرَانَا أَحَدٌ، فَقُلْنَا‏:‏ لَوْ قَدِمْنَا، فَخَرَجَ النَّبِيُّ صلى الله عليه وسلم مِنْ صَلاَةِ الْفَجْرِ، قُلْنَا‏:‏ نَحْنُ الْفَرَّارُونَ، قَالَ‏:‏ أَنْتُمُ الْعَكَّارُونَ، فَقَبَّلْنَا يَدَهُ، قَالَ‏:‏ أَنَا فِئَتُكُمْ‏.‏
