Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said to me: "How will you be when you are among the worthless dregs of people, whose covenants and trusts have become corrupted, and who fall into disagreement and become like this," then he put his fingers into one another. I said: O Messenger of Allah, what should I do? He said: "Take what you know, leave what you consider evil, concern yourself with your own particular affair, and beware of the common people (and their affairs)."
