Chapter 1: The Book of the Sunnah
It was narrated that Abu Harun Al-' Abdi said: "When we came to Abu Sa' eed Al-Khudri, he would say: 'Welcome, in accordance with the injunction of the Messenger of Allah, for the Messenger of Allah said to us: "The people will follow you; they will come to you from all parts of the earth seeking to understand the religion. So when they come to you, take care of them."
