Chapter: Gifts are permissible for the Prophet (saws) and Banu Hashim and Banu Al-Muttalib, even if the giver acquired it by way of charity. When the receipient takes possession of Charity, it is no longer described as charity, and it is permissible for anyone for whom charity is otherwise unlawful
