Abi Sa'id al-Khudri said (may Allah the Exalted be well pleased with him):

"The Prophet (ﷺ) would perform the mid-morning ritual prayer so often that we would say: “He does not omit it,” and he would omit it so often that we would say: “He does not perform it!”

حَدَّثَنَا زِيَادُ بْنُ أَيُّوبَ الْبَغْدَادِيُّ، قَالَ‏:‏ حَدَّثَنَا مُحَمَّدُ بْنُ رَبِيعَةَ، عَنْ فُضَيْلِ بْنِ مَرْزُوقٍ، عَنْ عَطِيَّةَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ‏:‏ كَانَ النَّبِيُّ صلى الله عليه وسلم، يُصَلِّي الضُّحَى حَتَّى نَقُولَ‏:‏ لا يَدَعُهَا، وَيَدَعُهَا حَتَّى نَقُولَ‏:‏ لا يُصَلِّيهَا‏.‏
