The Messenger of Allah ﷺ would offer the Zuhr prayer while the sunlight was present in her apartment before it ascended (the walls).
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي الْعَصْرَ وَالشَّمْسُ فِي حُجْرَتِهَا قَبْلَ أَنْ تَظْهَرَ
Messenger of Allah ﷺ used to offer the ʿAsr prayers at a time when the sunshine was still inside my chamber and no shadow had yet appeared in it.
أَنَّ رَسُولَ اللَّهِ ﷺ صَلَّى الْعَصْرَ وَالشَّمْسُ فِي حُجْرَتِهَا لَمْ يَظْهَرِ الْفَىْءُ مِنْ حُجْرَتِهَا
'A'isha?, the wife of the Apostle ﷺ narrated it to me that the Messenger of Allah ﷺ used to say the afternoon prayer, when the light of the sun was there in her apartment before it went out (of it).
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي الْعَصْرَ وَالشَّمْسُ فِي حُجْرَتِهَا قَبْلَ أَنْ تَظْهَرَ
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
ذِكْرُ وَصْفِ ارْتِفَاعِ الشَّمْسِ فِي الْوَقْتِ الَّذِي كَانَ يُصَلِّي فِيهِ ﷺ صَلَاةَ الْعَصْرِ
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. (Using translation from Nasāʾī 505)
«أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي الْعَصْرَ وَالشَّمْسُ فِي حُجْرَتِهَا لَمْ يَظْهَرِ الْفَيْءُ فِي حُجْرَتِهَا»
Messenger of Allah ﷺ used to offer the ʿAsr prayers at a time when the sunshine was still inside my chamber and no shadow had yet appeared in it. (Using translation from Bukhārī 545)
أَنَّ رَسُولَ اللهِ ﷺ «صَلَّى صَلَاةَ الْعَصْرِ وَالشَّمْسُ فِي حُجْرَتِهَا لَمْ يَظْهَرِ الْفَيْءُ»
