وَحَدَّثَنِى حَرْمَلَةُ بْنُ يَحْيَى أَخْبَرَنَا ابْنُ وَهْبٍ أَخْبَرَنِى يُونُسُ عَنِ ابْنِ شِهَابٍ قَالَ أَخْبَرَنِى عُرْوَةُ بْنُ الزُّبَيْرِ أَنَّ عَائِشَةَ زَوْجَ النَّبِىِّ -صلى الله عليه وسلم- أَخْبَرَتْهُ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- كَانَ يُصَلِّى الْعَصْرَ وَالشَّمْسُ فِى حُجْرَتِهَا لَمْ يَظْهَرِ الْفَىْءُ فِى حُجْرَتِهَا.

'Urwah bin Az-Zubair narrated that 'Aishah, the wife of the Prophet (s.a.w), told him that the Messenger of Allah (s.a.w) used to pray 'Asr when the (rays of the) sun was in her apartment and the shadow had not appeared in her apartment.
