Sunan An-Nasa'i

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
