Sahih al-Bukhari, Hadith 545 ⓘ
Narrated `Aisha: Allah's Messenger used to offer the `Asr prayers at a time when the sunshine was still inside my chamber and no shadow had yet appeared in it.
حَدَّثَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى الْعَصْرَ وَالشَّمْسُ فِي حُجْرَتِهَا، لَمْ يَظْهَرِ الْفَىْءُ مِنْ حُجْرَتِهَا.
