I asked Anas b. Malik: Narrate to us what you heard the Messenger of Allah ﷺ say. He said: When we travelled along with the Messenger of Allah ﷺ, we would say: Did the sun pass the meridian or not? But he (the Prophet) would offer the noon prayer and then proceed.
سَمِعْتَ مِنْ رَسُولِ اللَّهِ ﷺ قَالَ كُنَّا إِذَا كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ فِي السَّفَرِ فَقُلْنَا زَالَتِ الشَّمْسُ أَوْ لَمْ تَزُلْ صَلَّى الظُّهْرَ ثُمَّ ارْتَحَلَ
[Machine] I heard Anas ibn Malik saying, "When we were with the Prophet ﷺ on a journey, whenever the sun would set or it was about to set, he would pray the noon prayer (Dhuhr) and then we would depart."
سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ كُنَّا إِذَا كُنَّا مَعَ النَّبِيِّ ﷺ فِي سَفَرٍ فَقُلْنَا زَالَتِ الشَّمْسُ أَوْ لَمْ تَزُلْ صَلَّى الظُّهْرَ ثُمَّ ارْتَحَلَ
"عَنْ أنَسٍ قَالَ: كُنّا إذا كُنَّا مع النَّبِىِّ ﷺ في السَّفَرِ قُلنَا: أزَالَتِ الشَّمْسُ أَوْ لَمْ تَزل صَلَّى الظُّهْرَ ثُمَّ ارْتَحَلَ".
