I heard 'Adi b. Hatim say that a person asked that and then narrated (the hadith) like one (mentioned above), but he made this addition:" Here are four hundred (dirhams) for you out of my gift."
The Book of Oaths - Sahih Muslim 1651f Commentary
This narration from 'Adi b. Hatim concerns the matter of oaths and their expiation, wherein a person offered four hundred dirhams as voluntary charity beyond the required expiation.
Scholarly Analysis
The addition "Here are four hundred dirhams for you out of my gift" demonstrates the permissibility of giving voluntary charity beyond obligatory expiations, reflecting the believer's desire for additional divine reward.
Classical scholars interpret this as evidence that voluntary acts of worship may accompany obligatory ones, and that exceeding minimum requirements in matters of expiation is commendable when done with sincere intention.
Legal Implications
This narration establishes that while fulfilling the basic requirements of oath expiation suffices, additional charity is praiseworthy and increases one's spiritual rewards without invalidating the original expiation.
The phrasing "out of my gift" indicates the voluntary nature of this additional charity, distinguishing it from the obligatory expiation amount required by Islamic law.
