And it was narrated to us by Muhammad ibn Abi 'Umar al-Makki, who said: 'Abd al-'Aziz al-Darawardi narrated to us, from Yazid ibn al-Had, from Muhammad ibn Ibrahim, from 'Isa ibn Talhah, from Abu Hurayrah, that the Messenger of Allah (peace be upon him) said: "Indeed, a servant may speak a word without realizing what it contains, and by it he will plummet into the Fire a distance greater than that between the East and the West."
