Hammad bin Zayd حماد بن زيد بن درهم الأزدي الأزرق · The Book of Jihad

"I heard Jabir say: 'A man said on the day of Uhud: If I am killed in the cause of Allah, where do you think I will be? He said: In Paradise. He threw down some dates that were in his hand and fought until he was killed.'"

"Allah laughs at two men, one of whom killed the other but they both entered Paradise. The first one fought in the cause of Allah and was killed, then Allah accepted the repentance of the one who killed him, and he fought and was martyred."
