question #3 Sahih Muslim 623, Book 5, Hadith 247 : What can be learned from the actions of the companions in maintaining the traditions of the Prophet’s prayers?

We offered the noon prayer with Umar b. ‘Abd al-‘Aziz. We then set out till we came to Anas b. Malik and found him busy in saying the afternoon prayer. I said to him: O uncle! which is this prayer that you are offering? He said: It is the afternoon prayer and this is the prayer of the Messenger of Allah (ﷺ) that we offered along with him.
