Usamah bin Zaid said I asked Apostle of Allaah ﷺ where will you encamp tomorrow? (This is asked on the occasion of his Hajj). He replied “Did ‘Aqil leave any house for us?” He again said “We shall encamp in the valley (Khaif) of Banu Kinanah where the Quraish took an oath upon disbelief, that is, Al Muhassab.” The oath was that Banu Kinanah concluded a pact with the Quraish against Banu Hashim “they would have no marital relationship with them, nor would give them accommodation nor would have any commercial ties with them.” Al Zuhri said Al Khaif means valley. (Using translation from Abū Dāʾūd 2010)
قُلْتُ يَا رَسُولَ اللهِ أَيْنَ تَنْزِلُ؟ وَذَلِكَ فِي حَجَّتِهِ قَالَ وَهَلْ تَرَكَ لَنَا عُقَيْلٌ مَنْزِلًا ثُمَّ قَالَ نَحْنُ نَازِلُونَ غَدًا بِخَيْفِ بَنِي كِنَانَةَ حَيْثُ تَقَاسَمُوا الْكُفَّارَ يَعْنِي بِذَلِكَ الْمُحَصَّبَ وَذَلِكَ أَنَّ قُرَيْشًا وَكِنَانَةَ تَحَالَفَتْ عَلَى بَنِي هَاشِمٍ أَنْ لَا يُنَاكِحُوهُمْ وَلَا يُبَايِعُوهُمْ وَلَا يُؤْوُهُمْ قَالَ الزُّهْرِيُّ وَالْخَيْفُ الْوَادِي
