In Makkah Mukarramah, there once lived a man named Ibnu Thaabit (rahimahullah). He used to perform haj every year, and thereafter used to travel to Madinah Munawwarah to present salaam at the blessed grave of Rasulullah (sallallahu ‘alaihi wasallam). He did this for seventy years consecutively.
Once, it so happened that for some reason, he could not go to Madinah Munawwarah to visit the grave of Rasulullah (sallallahu ‘alaihi wasallam). While remaining at home, seated in his room, he was overcome by sleep. While asleep, he saw Rasulullah (sallallahu ‘alaihi wasallam) saying to him in a dream, “O Ibnu Thaabit! This year, you did not come to meet me. For this reason, I have now come to meet you.”
