The answer is no.
May he take from it for his own maintenance? This requires further detail, which he clarifies in his statement:
“The poor guardian may eat”—that is, the one who has no means sufficient for him, whether from the earnings of his own hand, income from property, a salary, or an allowance. He has nothing besides the wealth of this orphan.
His statement, “from the wealth of his ward, whichever is less: his sufficient maintenance or his wage, without charge,” means that if we suppose his sufficient maintenance to be one thousand riyals and his wage to be five hundred riyals, then we give him five hundred, because it is the lesser amount. If he says, “This is not sufficient for me; I am still poor,” we say: You are entitled only to the wage.
Conversely, if his wage is one thousand riyals while his sufficient maintenance is five hundred, we give him five hundred. There is no difficulty in this case. The difficulty lies in the first scenario: when the wage is less than sufficient maintenance, he will remain poor. Yet the apparent meaning of the noble verse—“But if he is poor, let him eat from it according to what is fair” [al-Nisa’ 4:6]—is that he may eat according to what is fair; and if the wage is less, his sufficient maintenance should be completed for him. Accordingly, we say: he may take what suffices for his maintenance, whether it equals the wage, is less than it, or exceeds it, for this is the apparent meaning of the Quran: “But if he is poor, let him eat from it according to what is fair.”
If this guardian then asks, “When I take from the property of the legally restricted person, should my maintenance be that of wealthy people, poor people, or people of moderate means?”
The answer is that Allah says, “according to what is fair.” If it is according to what is fair, then we know that the poor have one standard of maintenance, the wealthy have another,
