Mishkat al-Masabih 5398

`Abdallah b. `Amr b. al- `As reported the Prophet (ﷺ) as saying, “How will you do when you are left among dregs of mankind whose covenants and guarantees have been impaired, who have disagreed and become thus?” intertwining his fingers. He asked what he ordered him to do and he replied, “Keep to what you approve, abandon what you disapprove, attend to your own affairs and avoid the generality.” A version has, “Keep to your house, control your tongue, accept what you approve, abandon what you disapprove, attend to your own affairs and leave alone the affairs of the generality.”
Tirmidhi transmitted it, calling it sahih.
