Pilgrimmage (Hajj)
Bukhari :: Book 2 :: Volume 26 :: Hadith 608
Narrated Ibn 'Umar :
Allah's Apostle used to go (for Hajj) via Ash-Shajara way and return via Muarras way; and no doubt, whenever Allah's Apostle went to Mecca, he used to offer the prayer in the Mosque of Ash-Shajara; and on his return, he used to offer the prayer at Dhul-Hulaifa in the middle of the valley, and pass the night there till morning.
