Battles (Kitab Al-Malahim)
Dawud :: Book 37 : Hadith 4329
Narrated Abdullah ibn Amr ibn al-'As:
When we were around the Apostle of Allah (peace_be_upon_him), he mentioned the period of commotion (fitnah) saying: When you see the people that their covenants have been impaired, (the fulfilling of) the guarantees becomes rare, and they become thus (interwining his fingers). I then got up and said: What should I do at that time, may Allah make me ransom for you? He replied: 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.
