Sahih al-Bukhari 6039
Narrated Al-Aswad:
I asked `Aisha what did the Prophet (ﷺ) use to do at home. She replied. "He used to keep himself busy 
serving his family and when it was time for the prayer, he would get up for prayer."
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، قَالَ سَأَلْتُ عَائِشَةَ مَا كَانَ النَّبِيُّ صلى الله عليه وسلم يَصْنَعُ فِي أَهْلِهِ قَالَتْ كَانَ فِي مِهْنَةِ أَهْلِهِ، فَإِذَا حَضَرَتِ الصَّلاَةُ قَامَ إِلَى الصَّلاَةِ‏.‏
