Musnad Ahmad 32:407

'Abd al-Rahman ibn Mahdi narrated to us, from Sufyan, from al-Zubayr—meaning Ibn 'Adi—who said: We complained to Anas ibn Malik about what we were encountering from al-Hajjaj. He said: "Be patient, for there does not come upon you a year or a day except that the one after it is worse than it, until you meet your Lord." I heard it from your Prophet, may Allah bless him and grant him peace.
