It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "How will you be when you remain among the worthless dregs of people, a people whose covenants and trusts have become corrupted, and who fall into disagreement and become like this?" And he interlaced his fingers. He said: O Messenger of Allah, what do you command me? He said: "Adopt what you know, leave what you consider evil, concern yourself with your own self in particular, and leave the common people (and their affairs)."
