Musannaf Ibn Abi Shaybah

Hazrat Abdullah bin Atik (may Allah be pleased with him) narrates that I heard the Messenger of Allah (peace and blessings be upon him) say: Whoever sets out for jihad in the way of Allah—while saying this, he joined his three fingers together—and then said: Where are those who strive in jihad? If he falls from his mount and dies, then his reward is guaranteed by Allah; or if something bites him, then his reward is guaranteed by Allah; or if he dies a natural death, then his reward is also guaranteed; and if he dies bearing the blow of the enemy, then he has attained a good abode.
