"I asked Anas bin Malik: 'How should I leave after I have prayed- to the right or to the left?' He said: 'I usually saw the Messenger of Allah (ﷺ) leave to the right.'
Sunan an-Nasa'i Book 13, Hadith 181
← Previous Hadith "I said to Jabir bin Samurah: 'Did you used to sit with the Messenger of Allah (ﷺ)?" He said: 'Yes.' When the Messenger of Allah (ﷺ) had prayed fajr, he would sit in the place where he had prayed until the sun rose, and his companions would talk and remember things from the time of Jahilliyah and recite poetry, and they would laugh and he would smile.'"

Sunan an-Nasa'i Book 13, Hadith 180 Next Hadith → "Abdullah said: 'No one among you should allow the Shaitan to give him wrong ideas by making him believe that he can only leave after praying by moving to his right, because I saw the Messenger of Allah (ﷺ) usually departing to the left.'"
