Sahih Bukhari | Volume 1 | Hadith Number 116

Narrated by 'Abdullah bin 'Umar
Once the Prophet led us in the 'Isha prayer during the last days of his life and after finishing it (the prayer) (with Taslim) he said: "Do you realize (the importance of) this night?" Nobody present on the surface of the earth tonight will be living after the completion of one hundred years from this night."
