In a narration from Abu Basir, reported from Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq عليه السلام who said: "Whoever withholds even a carat of Zakat is neither a believer nor a Muslim. This is the meaning of Allah’s سبحانه وتعالى statement: 'Until, when death comes to one of them, he says, "My Lord عز وجل, send me back, that I might do righteousness in that which I left behind"' (Surah Al-Mu’minun 23:99-100)." In another narration, it is stated: "And none of his prayers will be accepted."
