Musannaf Ibn Abi Shayba 28:509

Ibn ‘Ulayyah narrated to us, from Yunus, from al-Hasan, that the spies of Musaylimah captured two men from the Muslims and brought them to him. He said to one of them: "Do you testify that Muhammad is the Messenger of Allah?" He said: "Yes." He said: "Do you testify that Muhammad is the Messenger of Allah?" He said: "Yes." He said: "Do you testify that I am the Messenger of Allah?" He [the man] gestured toward his ears and said: "I am deaf." He [Musaylimah] said: "What is the matter with you? When I said to you 'testify that I am the Messenger of Allah,' you said 'I am deaf'?" He then ordered him to be killed. He said to the other: "Do you testify that Muhammad is the Messenger of Allah?" He said: "Yes." He said: "Do you testify that I am the Messenger of Allah?" He said: "Yes." So he released him. He came to the Prophet (peace and blessings of Allah be upon him) and said: "O Messenger of Allah, I am ruined." He said: "What is your situation?" They informed him of his story and the story of his companion. He said: "As for your companion, he proceeded upon his faith, and as for you, you took the concession."
