The Time Of The 'Asr Prayer
Sunan Ibn Majah
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ صَلَّى النَّبِيُّ ـ صلى الله عليه وسلم ـ الْعَصْرَ وَالشَّمْسُ فِي حُجْرَتِي لَمْ يُظْهِرْهَا الْفَىْءُ بَعْدُ .
It was narrated that 'Aishah said: "The Prophet prayed the 'Asr when the sun was shining into my room and there were no shadows yet."
