Hastening To Pray 'Asr
Sunan an-Nasai
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى صَلاَةَ الْعَصْرِ وَالشَّمْسُ فِي حُجْرَتِهَا لَمْ يَظْهَرِ الْفَىْءُ مِنْ حُجْرَتِهَا .
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.
