Muhammad ibn al-Muthanna and Ibn Bashshar narrated to us, both saying: Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, saying: I heard Abu Ishaq narrating from Abu al-Ahwas, from 'Abdullah ibn Mas'ud, who said: Indeed, Muhammad, peace be upon him, said: "Shall I not inform you of what al-'adhah is? It is the slanderous gossip that spreads among people." And indeed, Muhammad, peace be upon him, said: "A man continues to tell the truth until he is recorded as a truthful one, and he continues to lie until he is recorded as a liar."
