Harmalah ibn Yahya narrated to me: Ibn Wahb informed us: Yunus informed me, from Ibn Shihab, who said: Humayd ibn Abd al-Rahman ibn Awf narrated to me that Abu Hurayrah said: The Messenger of Allah, peace and blessings be upon him, said: "Time will draw near, knowledge will be taken away, tribulations will appear, stinginess will be cast into hearts, and al-haraj will increase." They said: "What is al-haraj?" He said: "Killing."
