893/1166 (Authentic chain of narration) from Sa'id al-Maqburi who said: I passed by Ibn Umar while he was with a man talking, so I approached them, and he struck my chest and said: "If you find two people talking, do not stand with them, nor sit with them, until you seek their permission." So I said: May Allah rectify you, O Abu Abd al-Rahman! I only hoped to hear some good from you both.
