سنن أبي داود

Narrated Ali ibn AbuTalib:

When the morning came, the Prophet (ﷺ) 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.
