Is it permissible for the guardian to dispose of the minor's money through charity (sadaqah), gift (hibah), and zakat?

A guardian is not permitted to dispose of a minor's property except in ways that are in the minor's best interest, such as engaging in trade that preserves and grows the wealth. He is not allowed to donate the minor's property or to show favoritism in its use. Scholars have differed on the obligation of Zakat (definition) on a minor's property. The majority of scholars hold that it is obligatory, and the guardian must disburse it, citing the Prophet's (peace be upon him) saying: "Whoever takes charge of an orphan who has property, let him invest it for him, and not leave it until Sadaqa consumes it." While Al-Awza'i held that it is obligatory but should not be disbursed until the minor reaches puberty, the Hanafis held that it is not obligatory. The correct view is that of the majority, so the guardian is obliged to disburse Zakat on the minor's property if it reaches the nisab (definition).
