maintenance is not a voluntary gift; rather, it is the fulfillment of an obligation, like zakah.
If, during his life-threatening illness, he acknowledges a debt owed to an heir, then the matter must be examined. If there are indications that establish his truthfulness, we act upon his acknowledgment. Otherwise, his acknowledgment is like his gift: it is neither valid nor accepted. For some people may not fear Allah: during a life-threatening illness, one of them may acknowledge something in favor of one of his heirs, saying, “I owe so-and-so such-and-such,” when this is not in fact the case.

If the heirs approve it, there is no objection. The heirs whose approval is recognized are those legally competent to make gifts, and their approval must be given after death, as will be mentioned.

This is based on the hadith of Sa‘d ibn Abi Waqqas, who sought the Prophet’s ﷺ permission, while ill, to give two-thirds of his wealth in charity—the two-thirds being two out of three. He said, “No.” He asked, “Then half”—and half is one out of
