(1) He is Abu al-Hasan ‘Abd al-Wahhab ibn ‘Abd al-Hakam ibn Nafi‘ al-Baghdadi al-Warraq. Abu Dawud, al-Nasa’ī, al-Tirmidhī, and others narrated from him; he accompanied Imam Ahmad (may Allah have mercy on him) and heard from him. al-Marwazī said: “I heard Ahmad ibn Hanbal say: ‘‘Abd al-Wahhab al-Warraq was a righteous man; may Allah grant others like him to attain the truth.’” And Ahmad (may Allah have mercy on him) said: “May Allah preserve him; you seldom see his like.” He died in 251 AH.
