Sahih al-Bukhari 591
Sahih al-Bukhari · Book 9: Times of the Prayers · To offer the missed Salat (prayers) and the like after the 'Asr prayer
Narrated Hisham's father:
حَدَّثَنَا مُسَدَّدٌ ، قَالَ حَدَّثَنَا يَحْيَى ، قَالَ حَدَّثَنَا هِشَامٌ ، قَالَ أَخْبَرَنِي أَبِي قَالَتْ، عَائِشَةُ ابْنَ أُخْتِي مَا تَرَكَ النَّبِيُّ صلى الله عليه وسلم السَّجْدَتَيْنِ بَعْدَ الْعَصْرِ عِنْدِي قَطُّ.
`Aisha (addressing me) said, "O son of my sister! The Prophet (ﷺ) never missed two prostrations (i.e. rak`at) after the `Asr prayer in my house."
