حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا مُعَاوِيَةُ بْنُ عَمْرٍو، حَدَّثَنَا أَبُو إِسْحَاقَ، عَنْ حُمَيْدٍ، قَالَ سَمِعْتُ أَنَسًا ـ رضى الله عنه ـ يَقُولُ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا غَزَا قَوْمًا لَمْ يُغِرْ حَتَّى يُصْبِحَ، فَإِنْ سَمِعَ أَذَانًا أَمْسَكَ، وَإِنْ لَمْ يَسْمَعْ أَذَانًا أَغَارَ بَعْدَ مَا يُصْبِحُ، فَنَزَلْنَا خَيْبَرَ لَيْلاً.
