Abu Dawud Book 12, Hadith Number 2904.
Chapter : Can a muslim inherit from an infidel.
Narated By Usamah b. Zaid : I said: Apostle of Allah, where will you stay tomorrow? This (happened) during his Hajj. He replied: Has ‘Aqil left any house for us? He then said: We shall stay at the valley of Banu Kinanah where the Quraish took an oath on unbelief. This refers to al-Muhassab. The reason is that Banu Kinanah made an alliance with the Quraish against Banu Hashim that they would have no marital connections with them, nor will have commercial transactions with them, nor will give them any refuge.
Al-Zuhri said: Khaif means valley.
