The Rites of Hajj (Kitab Al-Manasik Wa'l-Hajj)

Dawud :: Book 10 : Hadith 1930

Narrated Ali ibn AbuTalib:

When the morning came, the Prophet (peace_be_upon_him) stood at the mountain Quzah and said: This is Quzah, and this is a place of stationing, and the whole of al-Muzdalifah is a place of stationing. I sacrificed the animals here, and the whole of Mina is a place of sacrifice. So sacrifice in your dwellings.
