The times of the five prayers
Sahih Muslim
قَالَ عُرْوَةُ وَلَقَدْ حَدَّثَتْنِي عَائِشَةُ، زَوْجُ النَّبِيِّ صلى الله عليه وسلم أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُصَلِّي الْعَصْرَ وَالشَّمْسُ فِي حُجْرَتِهَا قَبْلَ أَنْ تَظْهَرَ .
'Urwah (also) said: 'A'isha?, the wife of the Apostle (ﷺ) narrated it to me that the Messenger of Allah (ﷺ) used to say the afternoon prayer, when the light of the sun was there in her apartment before it went out (of it).
