“’Amir al-Mu’minin (a.s.), once heard a man say, ‘A greedy person has more excuses than an unjust person has.’ He (the Imam) said, ‘What you said is false. An unjust person may repent, ask for forgiveness and return usurped property. A greedy person, upon exercising his greed, may withhold payment of zakat, charity, keeping proper relations with relatives, serving guests, spending (for deserving cause) for the sake of Allah and virtuous instances. (On the other hand), it is forbidden to admit a greedy person in the garden (paradise).’”
