That Messenger of Allah ﷺ used to offer the ʿAsr prayer while the sun was still shining in her Hujra (i.e. her dwelling place).  

كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّي الْعَصْرَ وَالشَّمْسُ لَمْ تَخْرُجْ مِنْ حُجْرَتِهَا  

Urwa said that A'isha, the wife of the Prophet ﷺ used to pray asr while the sunlight was pouring into her room, before the sun itself had become visible (i.e. because it was still high in the sky).  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي الْعَصْرَ وَالشَّمْسُ فِي حُجْرَتِهَا قَبْلَ أَنْ تَظْهَرَ  

The Messenger of Allah ﷺ said the afternoon prayer (at a time) when the (light) of the sun was there in my apartment. (Using translation from Muslim 611d)  

كَانَ رَسُولُ اللهِ ﷺ يُصَلِّي الْعَصْرَ وَالشَّمْسُ وَاقِعَةٌ فِي حُجْرَتِي  

[Machine] "The Messenger of Allah ﷺ used to pray the Asr prayer, while the sun was still shining in my room."  

كَانَ رَسُولُ اللهِ ﷺ يُصَلِّي الْعَصْرَ وَإِنَّ الشَّمْسَ لَطَالِعَةٌ فِي حُجْرَتِي  

The Messenger of Allah ﷺ said: “No prayer should be offered after ʿAsr unless the sun is bright and still high.” (Using translation from Aḥmad 610)   

قَالَ رَسُولُ اللَّهِ ﷺ «لَا يُصَلَّى *الْعَصْرِ إِلَّا أَنْ تَكُونَ الشَّمْسُ مُرْتَفِعَةٌ»  

"كَان النَّبِيُّ ﷺ يُصَلِّي العَصْر حِين تَخْرجُ الشَّمْس مِنْ حُجْرَتِي، وَكَانَ قَدْر حُجْرَتِي بَسْطَة (*) ".
