What are the rulings of zakat concerning a poor or sick brother, and is it permissible to give zakat to a brother within the limit of one-third only, and is it permissible to give zakat for several years in advance or to a debtor who has legal judgments against him, and how is zakat calculated on savings from monthly wages?

If your brother does not find enough for his basic needs, then he is poor and eligible for zakat. Paying zakat to him is more virtuous, for the Prophet, peace and blessings be upon him, said: "Charity given to a poor person is charity, and charity given to a relative is two: charity and upholding ties of kinship." He should be given from zakat what suffices his needs. Your zakat for the sick person is valid if he cannot find the expenses for treatment and meets the definition of poverty. Expediting zakat is permissible for a period not exceeding two years. It is permissible to pay zakat to a debtor who is unable to repay his debt, because he is among those in debt.
