Chapter 11: The Book of Prayer - Eclipses
' Amra reported that a Jewess came to 'A' isha to ask (about something) and said: May Allah protect you from the torment of the grave! 'A' isha said: Messenger of Allah, would people be tormented in the graves? The Messenger of Allah (ﷺ) said: (May there be) protection of Allah! The Messenger of Allah (ﷺ) mounted one morning on the ride, and the sun eclipsed. 'A' isha said: I came in the company of the women in the mosque from behind the rooms. The Messenger of Allah (way peace he upon him) dismounted from his ride and came to the place of worship where he used to pray. He stood up (to pray) and the people stood behind him. 'A' isha said: He stood for a long time. He then bowed and it was a long ruku'. He then raised his head and he stood for a long time, less than the first standing. He then bowed and his ruku' was long, but it was less than that (the first) ruku'. He then raised (his head) and the sun had become bright. He (the Holy Prophet) then said: I saw you under trial in the grave like the turmoil of Dajjal. 'Amra said: I heard 'A' isha say: I listened after this to the Messenger of Allah (ﷺ) seeking refuge from the torment of Fire and the torment of the grave.
