Sahih Bukhari Volume 1, Book 9, Hadith 550

حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ حَدَّثَنِي أَنَسُ بْنُ مَالِكٍ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي الْعَصْرَ وَالشَّمْسُ مُرْتَفِعَةٌ حَيَّةٌ، فَيَذْهَبُ الذَّاهِبُ إِلَى الْعَوَالِي فَيَأْتِيهِمْ وَالشَّمْسُ مُرْتَفِعَةٌ، وَبَعْضُ الْعَوَالِي مِنَ الْمَدِينَةِ عَلَى أَرْبَعَةِ أَمْيَالٍ أَوْ نَحْوِهِ

Narrated By 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.
