'Have you prayed 'Asr?' We said: 'No, we have just finished Zuhr.' He said: 'Pray 'Asr.' So we got up and prayed, and when we finished he said: 'I heard the Messenger of Allah (ﷺ) say: "That is the prayer of the hypocrite: he sits and delays 'Asr prayer until (the sun) is between the horns of the Shaitan, then he gets up and pecks four (Rak'ahs) in which he only remembers Allah a little.'"
Sunan an-Nasa'i Book 6, Hadith 18
