Once the Prophet (ﷺ) stood over one of the high buildings of Medina and then said (to the people), "Do you see what I see?" They said, "No." He said, "I see afflictions falling among your houses as rain drops fall."
Sahih al-Bukhari Book 92, Hadith 12
← Previous Hadith The Prophet (ﷺ) got up from his sleep with a flushed red face and said, "None has the right to be worshipped but Allah. Woe to the Arabs, from the Great evil that is nearly approaching them. Today a gap has been made in the wall of Gog and Magog like this." (Sufyan illustrated by this forming the number 90 or 100 with his fingers.) It was asked, "Shall we be destroyed though there are righteous people among us?" The Prophet (ﷺ) said, "Yes, if evil increased."

Sahih al-Bukhari Book 92, Hadith 11 Next Hadith → The Prophet (ﷺ) said, "Time will pass rapidly, good deeds will decrease, miserliness will be thrown (in the hearts of the people) afflictions will appear and there will be much 'Al-Harj." They said, "O Allah's Apostle! What is "Al-Harj?" He said, "Killing! Killing!" (See Hadith No. 63, Vol. 8)
