Narrated by Abu Huraira
The Prophet said, "Amongst the people preceding you there used to be 'Muhaddithun' (i.e. persons who can guess things that come true later on, as if those persons have been inspired by a divine power), and if there are any such persons amongst my followers, it is 'Umar bin Al-Khattab."
