[Machine] From the Prophet ﷺ, that he used to pray Asr when the sun is high and bright, then the man walks until he moves away from it towards Dhul-Hulayfah, which is six miles before the sunset. They both agreed upon the narration of Bashir ibn Abu Mas'ud in the last narration of Az-Zuhri from Urwah, with a different wording. As for the second witness...  

عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ «يُصَلِّي الْعَصْرَ وَالشَّمْسُ بَيْضَاءُ مُرْتَفِعَةٌ ثُمَّ يَسِيرُ الرَّجُلُ حَتَّى يَنْصَرِفَ مِنْهَا إِلَى ذِي الْحُلَيْفَةِ وَهِيَ سِتَّةُ أَمْيَالٍ قَبْلَ غُرُوبِ الشَّمْسِ» «قَدِ اتَّفَقَا عَلَى حَدِيثِ بَشِيرِ بْنِ أَبِي مَسْعُودٍ فِي آخِرِ حَدِيثِ الزُّهْرِيِّ عَنْ عُرْوَةَ بِغَيْرِ هَذَا اللَّفْظِ وَأَمَّا الشَّاهِدُ الثَّانِي»
