Sahih Bukhari Volume 9, Book 88, Hadith Number 188.

Narrated By Az-Zubair bin ‘Adi : We went to Anas bin Malik and complained about the wrong we were suffering at the hand of Al-Hajjaj. Anas bin Malik said, “Be patient till you meet your Lord, for no time will come upon you but the time following it will be worse than it. I heard that from the Prophet.”
