Narrated Aisha:

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

حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، حَدَّثَنَا أَنَسُ بْنُ عِيَاضٍ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، أَنَّ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي الْعَصْرَ وَالشَّمْسُ لَمْ تَخْرُجْ مِنْ حُجْرَتِهَا‏.‏
