Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates from Sayyiduna Abu Talhah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Giving charity to a poor person is only charity, but giving charity to a relative is both charity and upholding the ties of kinship."
