Sahih al-Bukhari, 1468

Rapporté par Abou Hourayra : Le Messager d’Allah (ﷺ) (p.b.u.h) a ordonné à une personne de collecter la Zakat, et cette personne est revenue lui dire qu’Ibn Jamil, Khalid bin Al-Walid et ‘Abbas bin ‘Abdul Muttalib avaient refusé de donner la Zakat. Le Prophète a dit : Qu’est-ce qui a poussé Ibn Jamil à refuser de donner la Zakat alors qu’il était pauvre et qu’Allah et Son Messager l’ont enrichi ? Mais vous êtes injustes de demander la Zakat à Khalid, car il garde son armure pour la cause d’Allah (pour le Jihad). Quant à ‘Abbas bin ‘Abdul Muttalib, il est l’oncle du Messager d’Allah (ﷺ) et la Zakat est obligatoire pour lui, et il doit la payer en double

Narrated Abu Huraira:Allah's Messenger (ﷺ) ordered (a person) to collect Zakat, and that person returned and told him that Ibn Jamil, Khalid bin Al-Walid, and `Abbas bin `Abdul Muttalib had refused to give Zakat." The Prophet said, "What made Ibn Jamil refuse to give Zakat though he was a poor man, and was made wealthy by Allah and His Apostle ? But you are unfair in asking Zakat from Khalid as he is keeping his armor for Allah's Cause (for Jihad). As for `Abbas bin `Abdul Muttalib, he is the uncle of Allah's Apostle (ﷺ) and Zakat is compulsory on him and he should pay it double
