Abu Hurairah said “Apostle of Allaah(ﷺ) said when intended to march from Mina we shall encamp tomorrow. The narrator then narrated something similar (as a previous tradition but he did not mention the opening words, nor did he mention the words “Al Khaif, Al Wadi(Khaif means Valley).”
Sunan Abi Dawud Book 11, Hadith 291
← Previous Hadith 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.

Sunan Abi Dawud Book 11, Hadith 290 Next Hadith → Nafi’ said “Ibn ‘Umar used to nap for a short while at Batha’ (i.e, Al Muhassab) and then enter Makkah.” He thought that Apostle of Allaah(ﷺ) used to do so.
