Musannaf Ibn Abi Shayba 3:2930

Waki’ narrated to us, from Mis’ar, from Ibrahim al-Saksaki, who said: I heard Ibn Abi Awfa say: Three things, whoever is safe from them, what is between him and the next Friday will be forgiven for him: that he does not speak a word that does not concern him, or [that he is not] harmed by his stomach, or that he speaks, or that he says "hush."
