Mustadrak al-Hakim — Hadith 8813

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that he said: I was sitting with the Prophet (peace and blessings be upon him) when he (peace and blessings be upon him) mentioned the tribulation (fitnah), or the tribulation was mentioned in his presence, and he (peace and blessings be upon him) said: "When you see that people's covenants have become corrupted, that regard for their trusts has vanished, and that they have become like this (intermingled)," and he (peace and blessings be upon him) interlaced his fingers to show it. (Abdullah says:) I rose and went to him (peace and blessings be upon him) and said: O Messenger of Allah, may Allah make me your ransom, what should I do at that time (to protect myself)? He (peace and blessings be upon him) said: "Keep control of your tongue, stay firmly in your house, adopt what you know to be right (according to the Shari'ah) and leave what you find to be wrong (objectionable), concern yourself only with reforming your own self, and leave aside the affairs of the common people."
This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
