I saw Allah's Messenger (ﷺ) pointing with his index and middle fingers, saying. "The time of my Advent and the Hour are like these two fingers."
Sahih al-Bukhari Book 65, Hadith 457
← Previous Hadith Abu Huraira said, "Allah's Messenger (ﷺ) said, 'Between the two sounds of the trumpet, there will be forty." Somebody asked Abu Huraira, "Forty days?" But he refused to reply. Then he asked, "Forty months?" He refused to reply. Then he asked, "Forty years?" Again, he refused to reply. Abu Huraira added. "Then (after this period) Allah will send water from the sky and then the dead bodies will grow like vegetation grows, There is nothing of the human body that does not decay except one bone; that is the little bone at the end of the coccyx of which the human body will be recreated on the Day of Resurrection." (See Hadith No. 338)

Sahih al-Bukhari Book 65, Hadith 456 Next Hadith → The Prophet (ﷺ) said, "Such a person as recites the Qur'an and masters it by heart, will be with the noble righteous scribes (in Heaven). And such a person exerts himself to learn the Qur'an by heart, and recites it with great difficulty, will have a double reward."
