Abu Dawood: Hadith 2538

Amr ibn Uqaysh had given usurious loans in pre-Islamic period; so he disliked to embrace Islam until he took them. He came on the day of Uhud and asked: Where are my cousins? They (the people) replied: At Uhud. He asked: Where is so-and-so? They said: At Uhud. He asked: Where is so-and-so? They said: At Uhud. He then put on his coat of mail and rode his horse; he then proceeded towards them. When the Muslims saw him, they said: Keep away, Amir. He said: I have become a believer. He fought until he was wounded. He was then taken to his family wounded. Sa'd ibn Mu'adh came to his sister: Ask him (whether he fought) out of partisanship, out of anger for them, or out of anger for Allah. He said: Out of anger of Allah and His Apostle. He then died and entered Paradise. He did not offer any prayer for Allah.
