Sayyiduna Umar (may Allah be pleased with him) had appointed Umair bin Saeed as the governor of Homs. On one occasion, Sayyiduna Umar (may Allah be pleased with him) said to him: "I am going to ask you a question, do not hide anything from me." He replied: "Whatever I know, I will not hide." He (Umar) asked: "What do you consider to be the most dangerous thing for the Muslim Ummah?" He replied: "Misguiding leaders." Sayyiduna Umar (may Allah be pleased with him) said: "You have spoken the truth. The Prophet (peace and blessings be upon him) had informed me of this."
