(42) باب حِفْظِ الْعِلْمِ
Narrated `Abdullah bin `Umar:
Once the Prophet (ﷺ) 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."
