صحيح البخاري

Narrated Abu Huraira:

On the Day of Nahr at Mina, the Prophet (ﷺ) said, "Tomorrow we shall stay at Khaif Bani Kinana where the pagans had taken the oath of Kufr (heathenism)." He meant (by that place) Al-Muhassab where the Quraish tribe and Bani Kinana concluded a contract against Bani Hashim and Bani `Abdul-Muttalib or Bani Al-Muttalib that they would not intermarry with them or deal with them in business until they handed over the Prophet (ﷺ) to them.
