It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that Musaylimah the Liar sent two men as envoys, one of whom was Ibn Uthal bin Hajar. The Messenger of Allah (peace and blessings be upon him) asked them: "Do you two bear witness that Muhammad (peace and blessings be upon him) is the Messenger of Allah?" They both replied: We bear witness that Musaylimah is the messenger of Allah. At this the Prophet (peace and blessings be upon him) said: "I believe in Allah and His messengers. If I were one to kill envoys of delegations, I would (certainly) have killed you both." Then (some time later), when Sayyiduna Ibn Mas'ud (may Allah be pleased with him) was in Kufah, the man who had been with Ibn Uthal (as an envoy) was brought before him, and he was a relative of his. He ordered that he be killed, and said to the people: "Do you know why I have had him killed?" The people said: "We do not know." He said: "Musaylimah sent him with Ibn Uthal bin Hajar, and the Messenger of Allah (peace and blessings be upon him) said (to the two of them): 'Do you two bear witness that Muhammad is the Messenger of Allah?' They said: 'We bear witness that Musaylimah is the messenger of Allah.' So the Prophet (peace and blessings be upon him) said: 'I believe in Allah and His messengers. If I were one to kill envoys, I would have killed you both.' That is why I have had him killed." Abu Wa'il (may Allah have mercy on him) said: "That man was (still) a disbeliever at that time."
