Hmam bin Yahya bin Dinar همام بن يحيى بن دينار · The Book of Jihad

"Allah, the Mighty and Sublime, has guaranteed to the one who strives in His cause, only going out for Jihad in His cause, and believing in His Word, that He will admit him to Paradise, or bring him back to his home from which he emerged, with whatever he has earned of reward, or spoils of war."
