In this glorious hadith, Muhammad gives jihadis the necessary financial incentive to kill non-Muslims on a large-scale.
In contrast to the previous scenario in which Muhammad took a 20% cut of all war booty, a jihadi can now keep all the personal belongings of the non-Muslim he murders. Every school of Islamic jurisprudence endorses this concept, with the approval of the relevant leader recommended if not required.
In this particular hadith, Muhammad's financial incentive inspired Abu Talhah to kill twenty infidels at the Battle of Hunayn, thus stealing divinely earning twenty people's property.
And in recognition of Muhammad’s contributions to the development of a murder and theft-based economy, I appeal to the Royal Swedish Academy of Sciences to award a Nobel Prize in Economics posthumously.
