[Machine] The Messenger of Allah ﷺ used to perform the Duha prayer to the extent that we would say he never leaves it, and he would leave it to the extent that we would say he never performs it.
كَانَ رَسُولُ اللهِ ﷺ يُصَلِّي الضُّحَى حَتَّى نَقُولَ لَا يَتْرُكُهَا وَيَتْرُكُهَا حَتَّى نَقُولَ لَا يُصَلِّيهَا
"The Prophet would pray Ad-Duha until we would say: 'He will not leave it.' And he would leave it until we would say: 'He will not pray it.'" (Using translation from Tirmidhī 477)
كَانَ رَسُولُ اللهِ ﷺ يُصَلِّي الضُّحَى حَتَّى نَقُولَ لَا يَدَعُهَا وَيَدَعُهَا حَتَّى نَقُولَ لَا يُصَلِّيهَا
"عَنْ أَبِى سَعِيدٍ قَالَ: كَانَ رَسُولُ الله ﷺ يُصَلِّى حَتَى نَقَولَ: لَا يَدَعُهَا وَيَدَعُهَا حَتَى نَقُولَ: لَا يُصَلِّيهَا".
