I heard Allah's Messenger (ﷺ) saying; (It will be) from among the most wicked people who will be living at the time when the Hour will be established."
Sahih al-Bukhari Book 92, Hadith 18
← Previous Hadith The Prophet (ﷺ) said, "Near the establishment of the Hour, there will be the days of Al-Harj, and the religious knowledge will be taken away (vanish i.e. by the death of Religious scholars) and general ignorance will spread." Abu Musa said, "Al-Harj, in the Ethiopian language, means killing."

Sahih al-Bukhari Book 92, Hadith 17 Next Hadith → 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."
