Sahih Muslim , Book 40, Hadith 6868 (USC-MSA) ⓘ

Anas b. Malik reported: We were along with Umar between Mecca and Medina that we began to look for the new moon. And I was a man with sharp eye- sight, so I could see it, but none except me saw it. I began to say to 'Umar: Don't you see it? But he would not see it. Thereupon Umar said: I would soon be able to see it (when it will shine more brightly). I lay upon bed. He then made a mention of the people of Badr to us and said: Allah's Messenger showed us one day before (the actual battle) the place of death of the people (participating) in (the Battle) of Badr and he was saying: This would be the place of death of so and so tomorrow, if Allah wills. Umar said: By Him Who sent him with truth, they did not miss the places (of their death) which Allah's Messenger had pointed for them. Then they were all thrown in a well one after another. Allah's Messenger then went to them and said: O, so and so, the son of so and so; O so and so, the son of so and so, have you found correct what Allah and His Messenger had promised you? I have, however, found absolutely true what Allah had promised with me. Umar said: Allah's Messenger, how are you talking with the bodies without soul in them. Thereupon he said: You cannot hear more distinctly than (their hearing) of what I say, but with this exception that they have not power to make any reply.
