160 – Ahmad ibn Ibrahim narrated to us; he said: Zakariyya al-Marwazi related: A man brought a written volume to Abu Jamil and said, “Will you carry this book with you?” He replied, “Not until I consult the porter.” The man then took it to ʿAbd Allah ibn al-Mubarak and said, “O Abu ʿAbd al-Rahman, will you carry this book with you?” He answered, “Hand it to the servant.” The man remarked, “I first went to Abu Jamil and he said, ‘Not until I consult the porter.’” Ibn al-Mubarak responded, “And who is capable of what Abu Jamil is capable of—twice over?”
