Abu Imran al-Jawni (may Allah have mercy on him) says that Sayyiduna Umar (may Allah be pleased with him) wrote to Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him): Notable people will always bring the needs of the people to you, so honour them; and it is sufficient for a weak Muslim that he is treated fairly in justice and in distribution.
