The Prophet of Allah, sallallaahu ‘alayhi wa sallam, became angry at those among them who withheld their obligatory charity

“The Messenger of Allah, sallallaahu ‘alayhi wa sallam, sent `Umar to collect charity, and it was said that Ibn Jameel, Khaalid ibn Al-Waleed, and Al-`Abbaas, the uncle of Messenger of Allah, sallallaahu ‘alayhi wa sallam, withheld their charity. The Messenger of Allah, sallallaahu ‘alayhi wa sallam, said: ‘Why does Ibn Jameel withhold charity, even though he was poor and Allah made him rich? As for Khaalid, then surely you are oppressing Khaalid. He is a man who has kept his armor, weapons, and riding beasts for Allah’s Sake [in Jihaad]; as for Al-`Abbaas, I have already taken two years’ worth of charity from him.’”
