Ahmad (may Allah have mercy on him) relates: I heard Muhammad bin Mansur al-Qurashi (may Allah have mercy on him) saying: "I said to Ma'ruf al-Karkhi (may Allah have mercy on him): O Abu Mahfuz! Have you seen anyone in this city who has followed the way of the Abdal (the friends of Allah)? He remained silent, then said: 'O Allah, except for the one who is called Bishr al-Ummi.'"
Muhammad bin Mansur (may Allah have mercy on him) relates: I heard Khalaf bin Tamim (may Allah have mercy on him) saying that Bishr al-Ummi (may Allah have mercy on him) said: "Brothers made on the basis of generosity and nobility are dearer to us than brothers made on the basis of wealth and comfort."
