Times of the Prayers
Bukhari :: Book 1 :: Volume 10 :: Hadith 525
Narrated Anas bin Malik:
Allah's Apostle used to offer the 'Asr prayer at a time when the sun was still hot and high and if a person went to Al-'Awali (a place) of Medina, he would reach there when the sun was still high. Some of Al-'Awali of Medina were about four miles or so from the town.
