Musannaf Ibn Abi Shayba 3:2254

Ghundar narrated to us, from Shu'bah, from 'Amr ibn Murrah, from Salim ibn Abi al-Ja'd, who said: It was said to Thawban, "Narrate to us from the Messenger of Allah (may Allah bless him and grant him peace)." He said, "You lie about me. I heard the Messenger of Allah (may Allah bless him and grant him peace) say: 'There is no Muslim who prostrates a prostration to Allah, except that Allah raises him a degree by it, or removes a sin from him by it.'"
