How do we reconcile between the following two narrations?
1. If the wife or treasurer spends from the owner’s wealth then both will get equal/full reward [… min ghayri ay yunqasa min ujurihim shayan.]
2. The Hadith in Sahih Muslim as well, where it appears both will share the reward half half in the case where the slave gives sadaqah from his master’s wealth. [... wal ajru bainakuma nisfan.]
