Sahih Muslim 621 c
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.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 .
