From Sahih Bukhari (Hadith 3882):
Narrated Abu Huraira: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. (See Hadith)
