Musnad Ahmad 32:539

Hassan narrated to us, Hammad ibn Salamah narrated to us, from Thabit al-Bunani, from Anas ibn Malik, that he said: When this verse was revealed: "O you who have believed, do not raise your voices above the voice of the Prophet" [Al-Hujurat: 2] until the end of the verse, Thabit ibn Qays sat in his house and said: "I am among the people of the Fire," and he stayed away from the Prophet, peace and blessings of Allah be upon him. The Prophet, peace and blessings of Allah be upon him, asked Sa'd ibn Mu'adh: "O Abu 'Amr, what is the matter with Thabit? Is he ill?" Sa'd said: "He is my neighbor, and I do not know of any illness he has." Sa'd went to him and mentioned to him what the Messenger of Allah, peace and blessings of Allah be upon him, had said. Thabit said: "This verse was revealed, and you all know that I am the loudest of you in voice before the Messenger of Allah, peace and blessings of Allah be upon him, so I am among the people of the Fire." Sa'd mentioned that to the Prophet, peace and blessings of Allah be upon him, and the Messenger of Allah, peace and blessings of Allah be upon him, said: "Rather, he is among the people of Paradise."
