Narrated Asma' bint Abu Bakr:

I came to `Aisha during the solar eclipse. The people were standing (offering prayer) and she too, was standing and offering prayer. I asked, "What is wrong with the people?" She pointed towards the sky with her hand and said, Subhan Allah!'' I asked her, "Is there a sign?" She nodded with her head meaning, yes. When Allah's Messenger (ﷺ) finished (the prayer), he glorified and praised Allah and said, "There is not anything that I have not seen before but I have seen now at this place of mine, even Paradise and Hell. It has been revealed to me that you people will be put to trial nearly like the trial of Ad-Dajjal, in your graves. As for the true believer or a Muslim (the sub-narrator is not sure as to which of the two (words Asma' had said) he will say, 'Muhammad came with clear signs from Allah, and we responded to him (accepted his teachings) and believed (what he said)' It will be said (to him) 'Sleep in peace; we have known that you were a true believer who believed with certainty.' As for a hypocrite or a doubtful person, (the sub-narrator is not sure as to which word Asma' said) he will say, 'I do not know, but I heard the people saying something and so I said the same.' "
