I asked the Prophet ﷺ during his Hajj, "O Messenger of Allah ﷺ! Where will you stay tomorrow?" He said, "Has ʿAqil left for us any house?" He then added, "Tomorrow we will stay at Khaif Bani Kinana, i.e. Al-Muhassab, where (the Pagans of) Quraish took an oath of Kufr (i.e. to be loyal to heathenism) in that Bani Kinana got allied with Quraish against Bani Hashim on the terms that they would not deal with the members of the is tribe or give them shelter." (Az-Zuhri said, "Khaif means valley.") (See Hadith No. 659, Vol. 2)
قُلْتُ يَا رَسُولَ اللَّهِ أَيْنَ تَنْزِلُ غَدًا فِي حَجَّتِهِ قَالَ وَهَلْ تَرَكَ لَنَا عَقِيلٌ مَنْزِلاً ثُمَّ قَالَ نَحْنُ نَازِلُونَ غَدًا بِخَيْفِ بَنِي كِنَانَةَ الْمُحَصَّبِ حَيْثُ قَاسَمَتْ قُرَيْشٌ عَلَى الْكُفْرِ وَذَلِكَ أَنَّ بَنِي كِنَانَةَ حَالَفَتْ قُرَيْشًا عَلَى بَنِي هَاشِمٍ أَنْ لاَ يُبَايِعُوهُمْ وَلاَ يُئْوُوهُمْ قَالَ الزُّهْرِيُّ وَالْخَيْفُ الْوَادِي
