After some time, when Islam had penetrated into almost every home in Madinah Munawwarah, we called a meeting in which we deliberated over the plight of Rasulullah (sallallahu ‘alaihi wasallam). We thought to ourselves, “How much longer are we going to leave Rasulullah (sallallahu ‘alaihi wasallam) in this condition, wandering through the mountains of Makkah Mukarramah in a state of worry and fear?”

Thereafter, at the time of Haj that year, seventy of us came from Madinah Munawwarah to Makkah Mukarramah…”
