It was narrated from Anas:
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.
