Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Noble Prophet (peace and blessings be upon him) sent Sayyiduna Umar (may Allah be pleased with him) to collect zakat. When he returned, he complained about Sayyiduna Abbas (may Allah be pleased with him) and said: He did not pay his zakat to me. The Noble Prophet (peace and blessings be upon him) said: "O Umar! Do you not know that a man's uncle is in the place of his father? Sayyiduna Abbas (may Allah be pleased with him) had already paid two years' zakat together in advance." The narrator has transmitted the name of another narrator as Ubaydullah bin Umar, but what he meant was that this narration is transmitted from Muhammad bin Ubaydullah; and Allah knows best.
