Sunan Ibn Majah 2942

It was narrated that Usamah bin Zaid said:“I said: ‘O Messenger of Allah, where will you stay tomorrow?’ That was during his Hajj. He said: ‘Has ‘Aqil left us any house?’ Then he said: ‘Tomorrow we will stay in the valley of Banu Kinanah, Muhassab where the Quraish swore an oath of disbelief.’” That was where the Banu Kinana had sworn an oath with the Quriash against Banu Hashim, that they would not intermarry with them or engage in trade with them. Ma’mar said: “Zuhri said: Khaif means a valley.’”
