Sunan an-Nasa'i 2074
It was narrated that Anas said:
"We were with 'Umar between Makkah and Al-Madinah, when he strted to tell us about the people of Badr. He said: The Messenger of Allah showed us the day before where they (the disbelivers) would fall. He said: This is the place where so-and-so will fall tomorrow, if Allah wills.' 'Umar said: 'By the One Who sent him with the truth! They did not miss those places, They were placed in a well and the Prophet came to them and called out: O so-and-so, son of so-and-so! O so-and-so, son of so-andso! Have you found what your Lord promised to be true? Of I have found what allah promised me to be true. 'Umar said: 'Are you speaking to bodies in which there are no souls?' He said: 'You do not hear what I say any better than they do."'
