[Machine] The Prophet of Allah, may ﷺ , used to pray four units of prayer before noon when the sun would set.  

كَانَ نَبِيُّ اللهِ ﷺ إِذَا زَالَتِ الشَّمْسُ «صَلَّى أَرْبَعَ رَكَعَاتٍ قَبْلَ الظُّهْرِ حِينَ تَزُولُ الشَّمْسُ»  

The Prophet ﷺ never omitted four rak'ahs before the noon prayer, and two rak'ahs before the dawn prayer. (Using translation from Abū Dāʾūd 1253)  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ «لَا يَدَعُ أَرْبَعًا قَبْلَ الظُّهْرِ وَرَكْعَتَيْنِ قَبْلَ الْغَدَاةِ»  

I offered with Messenger of Allah ﷺ a two rakʿat prayer before the Zuhr prayer and two rakʿat after the Zuhr prayer, two rakʿat after Jumua, Maghrib and ʿIsha' prayers. (Using translation from Bukhārī 1169)   

أَنَّ النَّبِيَّ ﷺ كَانَ «يُصَلِّي قَبْلَ الظُّهْرِ رَكْعَتَيْنِ وَبَعْدَ الظُّهْرِ رَكْعَتَيْنِ وَبَعْدَ الْمَغْرِبِ رَكْعَتَيْنِ وَبَعْدَ الْعِشَاءِ رَكْعَتَيْنِ»  

It was narrated from ʿAli ؓ that The Prophet ﷺ prayed four [rakʿahs] before Zuhr. (Using translation from Aḥmad 1258)   

أَنَّ النَّبِيَّ ﷺ كَانَ «يُصَلِّي قَبْلَ الظُّهْرِ أَرْبَعًا»  

[Machine] About the prayer of the Messenger of Allah? She said, "He used to pray four before Dhuhr, then he would go out and pray, then he would return and pray two Rak'ahs, then he would go out to Al-Maghrib, then he would return and pray two Rak'ahs."  

عَنْ صَلَاةِ رَسُولِ اللهِ ﷺ؟ فَقَالَتْ كَانَ «يُصَلِّي أَرْبَعًا قَبْلَ الظُّهْرِ ثُمَّ يَخْرُجُ فَيُصَلِّي ثُمَّ يَرْجِعُ فَيُصَلِّي رَكْعَتَيْنِ ثُمَّ يَخْرُجُ إِلَى الْمَغْرِبِ ثُمَّ يَرْجِعُ فَيُصَلِّي رَكْعَتَيْنِ»
