I replied, “I had no food but Zamzam water. I grew stout until the folds of fat on my belly formed, and I felt no weakness from hunger.” He said: … and then recounted it.
Abu Bakr said, “Messenger of Allah, peace and blessings be upon him, permit me to feed him tonight.” The Messenger of Allah, peace and blessings be upon him, and Abu Bakr set out, and I went with them. Abu Bakr opened a door and began taking out handfuls of Ta'if raisins for us. This was the first food I ate there. Then I remained for as long as I remained, after which I came to the Messenger of Allah, peace and blessings be upon him. He said, “I have been directed toward a land of date palms, which I believe to be none other than Yathrib. Will you convey my message to your people? Perhaps Allah will benefit them through you and reward you on their account.”
So I went to Unays, who asked, “What have you done?” I replied, “I have embraced Islam and believed.” He said, “I have no desire for a religion other than yours; I too have embraced Islam and believed.” Then we went to our mother, and she said, “I have no desire for a religion other than yours; I too have embraced Islam and believed.” We then set out until we came to our tribe, Ghifar. Half of them embraced Islam, led in prayer by Ima' ibn Rahdah al-Ghifari, their chief. The other half said, “When the Messenger of Allah, peace and blessings be upon him, arrives in Medina, we shall embrace Islam.” When the Messenger of Allah, peace and blessings be upon him, arrived in Medina, the remaining half embraced Islam. Then Aslam came and said, “Messenger of Allah, peace and blessings be upon him, they are our brothers. We embrace Islam upon that which they embraced Islam.” So they embraced Islam, and the Messenger of Allah, peace and blessings be upon him, said, “May Allah forgive Ghifar, and may Allah grant safety to Aslam.”
