Sheikh Ahmed Muhammed Sufi (rahimahullah) says:

Once, I wandered around the desert for about thirteen months, suffering such great hunger and thirst that my skin dried out. In that condition of need, I reached Madinah Munawwarah.

On arriving in Madinah Munawwarah, I first greeted Rasulullah (sallallahu ‘alaihi wasallam) and his two companions, Hazrat Abu Bakr Siddeeq (radhiyallahu ‘anhu) and Hazrat Umar (radhiyallahu ‘anhu). Afterwards, I fell asleep.
