[Machine] The Messenger of Allah (PBUH) once came up to me on the day of Uhud when I was fourteen years old and patted me on the shoulder. It has been said that Hafsah and Abdullah embraced Islam before their father, and Abdullah was young at the time. His Islam was completed through his father's Islam, and Allah knows best. As for Abbas bin Abdul-Muttalib, he went to Badr with the polytheists and was captured until he ransomed himself and embraced Islam.
