It is narrated from Abdul Malik bin Umair that when Sayyiduna Umar bin Khattab (may Allah be pleased with him) dismissed Sayyiduna Khalid bin Walid (may Allah be pleased with him) and appointed Sayyiduna Abu Ubaidah bin Jarrah (may Allah be pleased with him) as the governor of Syria, Sayyiduna Khalid bin Walid (may Allah be pleased with him) said: The trustworthy and most reliable man of this Ummah has been sent to you. I heard the Messenger of Allah (peace and blessings be upon him) say that the trustworthy one of this Ummah is Abu Ubaidah bin Jarrah (may Allah be pleased with him). Sayyiduna Abu Ubaidah bin Jarrah (may Allah be pleased with him) said: I also heard the Messenger of Allah (peace and blessings be upon him) say that Khalid bin Walid is one of the swords of Allah and the best individual of his family.
