Times of the Prayers
Chapter: The mention of 'Isha' and 'Atama and whoever took the two names as one and the same
Narrated `Abdullah:
"One night Allah's Messenger (ﷺ) led us in the `Isha' prayer and that is the one called Al-`Atma [??] by the people. After the completion of the prayer, he faced us and said, "Do you know the importance of this night? Nobody present on the surface of the earth tonight will be living after one hundred years from this night." (See Hadith No. 575).
