It was narrated from 'Aishah that the Messenger of Allah ﷺ prayed 'Asr when the sun was in her room and the shadow had not appeared on her wall.  

أَنَّ رَسُولَ اللَّهِ ﷺ صَلَّى صَلاَةَ الْعَصْرِ وَالشَّمْسُ فِي حُجْرَتِهَا لَمْ يَظْهَرِ الْفَىْءُ مِنْ حُجْرَتِهَا  

"The Messenger of Allah ﷺ used to pray 'Asr, then a person could go to Quba'." One of them [1] said: "And he would come to them when they were prayed." The other said: "And the sub was still high." [1] Both Az-Zuhri and Ishaq bin 'Abdullah narrated it from Anas, so the reference is about them.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي الْعَصْرَ ثُمَّ يَذْهَبُ الذَّاهِبُ إِلَى قُبَاءٍ فَقَالَ أَحَدُهُمَا فَيَأْتِيهِمْ وَهُمْ يُصَلُّونَ وَقَالَ الآخَرُ وَالشَّمْسُ مُرْتَفِعَةٌ  

"The Messenger of Allah ﷺ used to pray 'Asr when the sun was still high and bright, and a person could go to Al-'Awali [1] when the sun was still high." [1] Al-'Awali is the southern most district of Al-Madinah, and it is very big. Its nearest limit is at a distance of about two miles from the center of Al-Madinah. While its furthest limit is about eight miles.  

أَنَّهُ أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي الْعَصْرَ وَالشَّمْسُ مُرْتَفِعَةٌ حَيَّةٌ وَيَذْهَبُ الذَّاهِبُ إِلَى الْعَوَالِي وَالشَّمْسُ مُرْتَفِعَةٌ  

"The Messenger of Allah ﷺ used to lead us in 'Asr prayer when the sun was still bright and high."  

كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّي بِنَا الْعَصْرَ وَالشَّمْسُ بَيْضَاءُ مُحَلِّقَةٌ  

"I heard Abu Umamah bin Sahl say: 'We prayed Zuhr with 'Umar bin 'Abdul-'Aziz, then we went out and entered upon Anas bin Malik, and we found him praying 'Asr.'" I said: "O uncle, what is this prayer that you prayed?" He said: "'Asr; this is the prayer of the Messenger of Allah ﷺ that we used to pray with him."  

الْعَصْرَ وَهَذِهِ صَلاَةُ رَسُولِ اللَّهِ ﷺ الَّتِي كُنَّا نُصَلِّي  

"We prayed at the time of 'Umar bin 'Abdul-'Aziz, then we went to Anas bin Malik and found him praying. when he finished he said to us: 'Have you prayed?' We said: 'We prayed Zuhr.' He said: 'I prayed 'Asr.' They said: 'You have prayed early.' He said: 'Rather I prayed as I saw my companions pray.'"  

لَنَا أَصَلَّيْتُمْ قُلْنَا صَلَّيْنَا الظُّهْرَ قَالَ إِنِّي صَلَّيْتُ الْعَصْرَ فَقَالُوا لَهُ عَجَّلْتَ فَقَالَ إِنَّمَا أُصَلِّي كَمَا رَأَيْتُ أَصْحَابِي يُصَلُّونَ
