حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ ، قَالَ حَدَّثَنِي إِبْرَاهِيمُ بْنُ سَعْدٍ ، عَنِ ابْنِ شِهَابٍ ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم حِينَ أَرَادَ حُنَيْنًا " مَنْزِلُنَا غَدًا إِنْ شَاءَ اللَّهُ بِخَيْفِ بَنِي كِنَانَةَ، حَيْثُ تَقَاسَمُوا عَلَى الْكُفْرِ " .
Allah's Messenger (ﷺ), while going out for the battle of Hunain, said, "Tomorrow Allah willing, we will encamp at Khaif Bani Kinana where the pagans(of Quraish) took the oath of Kufr (against the Prophet (ﷺ) i.e. to be loyal to heathenism, by boycotting Banu Hashim, the Prophet's folk.
