It is narrated from Ibn Mu’iz Sa’di, he says: I went out at the time of suhoor to give water to my horse. When I passed by the mosque of Banu Hanifa, I heard them saying: Indeed, Musaylimah is the Messenger of Allah. I went to Sayyiduna Abdullah (may Allah be pleased with him) and informed him of this incident. He sent the army, and they brought them back after capturing them. He demanded that they repent, and they repented, so he set them free, but he beheaded Abdullah bin Nuwahah. They said: How is it that you captured a people for one crime, then killed one and released another? I was present with the Messenger of Allah (peace and blessings be upon him), this man and Ibn Athal bin Hajar came to the Messenger of Allah (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said to them: Do you both testify that I am the Messenger of Allah? They said: We testify that indeed Musaylimah is the Messenger of Allah. Upon hearing this, the Noble Prophet (peace and blessings be upon him) said: I believe in Allah and His Messengers. If I were to kill any envoy, I would have killed both of you. He said: It is for this reason that I killed him.
