The Book of Mosques and Places of Prayer
5/34. Chapter:
It is recommended to pray `Asr early
Sahih Muslim
وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كُنَّا نُصَلِّي الْعَصْرَ ثُمَّ يَذْهَبُ الذَّاهِبُ إِلَى قُبَاءٍ فَيَأْتِيهِمْ وَالشَّمْسُ مُرْتَفِعَةٌ .
Anas b. Malik reported: We used to offer the 'Asr prayer, then one would go to Quba' and reach there and the sun would be still high.
