´'Abdullah bin 'Amr said:` "I heard the Messenger of Allah (ﷺ) say: 'There is no raiding party that goes out in the cause of Allah and acquires some spoils of war, but they have been given two-thirds of their reward in this world instead of in the Hereafter, and there remains one-third (in the Hereafter). And if they do not acquire any spoils of war, then all of their reward (will come in the Hereafter).'"
Explanation & Benefits
Hafiz Muhammad Ameen
It is understood from this that the one who acquires war booty (ghanimah) is deserving of a lesser reward, even if his intention was not for the booty. The full reward will be given only to the one who did not obtain any worldly benefit whatsoever. In no case can both be equal in reward; however, the person who fights jihad for the sake of booty will not receive any reward at all, whether he obtains the booty or not; rather, he will be deserving of punishment.
