Book Number: 004 / Hadith Number: 1930
Narated By Ali ibn AbuTalib : When the morning came, the Prophet (pbuh) 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.
