Answered by Shaykh Abu Usamah
Can Zakat be given to descendants of the Prophet Salallahu alaihi wassalam if they fulfill the other requirements of Zakat?

Al-Salam alaykum
Zakah cannot be given to the Banu Hashim i.e the descendants of `Ali, `Abbas, Ja`far, `Aqil and Harith bin Abdul Muttalib in honour of Rasulullah (sallallahu `alayhi wasallam). In a hadith recorded in Sahih Muslim it is stated: “This charity is the dirt of the (property) of people and is not permissible for Muhammad (sallallahu `alayhi wasallam) and his family.”
