Sahih al-Bukhari, Book 9, Hadith 67 (In-Book) ⓘ
Narrated Hisham's father: `Aisha (addressing me) said, "O son of my sister! The Prophet never missed two prostrations (i.e. rak`at) after the `Asr prayer in my house."
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.
