Al-Lu'lu Wal-Marjan 1229 — The Book of Al-Imâra (Concerning with ruling etc.)

Abu Hurairah Narrated from:

The Prophet صلى الله عليه وسلم said, "Allâh assigns for a person who participate (in holy battles) in Allâh's Cause and nothing causes him to do so except belief in Allâh and His Messengers, that he will be recompensed by Allâh either with a reward, or booty (if he survives) or will be admitted to Paradise (if he is killed in the battle as a martyr).”(The Prophet added): “Had I not found it difficult for my followers, then I would not remain behind any Sariya (army-unit) going for Jihâd and I would have loved to be martyred in Allâh’s Cause and then made alive, and then martyred and then made alive, and then again martyred in His Cause.” ( Sahih Al-Bukhâri, Hadith No. 35, Vol. 1)
