ولا تدفع إلى بني هاشم وهم: آل علي وآل عباس وآل جعفر وآل عقيل وآل حارث بن عبد المطلب ومواليهم
Translation: Zakat is not paid to Banū Hāshim: the households of Ali, Abbas, Jafar, Aqil and al-Harith ibn Abd al-Muttalib, or their mawālī.
The passage expressly enumerates these five lines together with their historical mawālī. The rule must not be shortened to one household alone.
Mawālī here describes a particular historical patronage/manumission relationship.
