It is narrated from Yazid bin Hurmuz that Najdah al-Haruri asked Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) about the relatives' share: whom is it for? He said: "You have written to me asking about the share of the relatives, whom it is for. It is for us. Sayyiduna Umar (may Allah be pleased with him) used to invite us (to agree) that from it he would arrange the marriages of our unmarried men and women, provide servants from it for our needy, and pay off from it the debts of our debtors. But we refused, insisting only that he hand it over to us; he refused, so we left it."
