"The Messenger of Allah ﷺ used to pray 'Asr, then a person could go to Quba'." One of them [1] said: "And he would come to them when they were prayed." The other said: "And the sub was still high." [1] Both Az-Zuhri and Ishaq bin 'Abdullah narrated it from Anas, so the reference is about them.
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي الْعَصْرَ ثُمَّ يَذْهَبُ الذَّاهِبُ إِلَى قُبَاءٍ فَقَالَ أَحَدُهُمَا فَيَأْتِيهِمْ وَهُمْ يُصَلُّونَ وَقَالَ الآخَرُ وَالشَّمْسُ مُرْتَفِعَةٌ
