Abu Bakr ibn Ishaq narrated to us, Ibn Abi Maryam informed us, Muhammad ibn Ja'far informed us, saying: al-'Ala' ibn 'Abd al-Rahman ibn Ya'qub, the freed slave of al-Huraqah, informed me, from his father, from Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, said: "Among the signs of the hypocrite are three: when he speaks, he lies; when he promises, he breaks his promise; and when he is entrusted, he betrays."
