صحيح البخاري

Narrated Anas bin Malik:

I went along with the Prophet (ﷺ) to Khaibar so as to serve him. (Later on) when the Prophet (ﷺ) returned he, on seeing the Uhud mountain, said, "This is a mountain that loves us and is loved by us." Then he pointed to Medina with his hand saying, "O Allah! I make the area which is in between Medina's two mountains a sanctuary, as Abraham made Mecca a sanctuary. O Allah! Bless us in our Sa` and Mudd (i.e. units of measuring)."
