Abu Harun (Abdi) narrated: We used to go to Abu Sa’eed to acquire knowledge. He would say, “Welcome as per the instructions of Allah’s Messenger. He (Allah’s Messenger (SAW) said, ‘People are following you. Indeed, people will come to you from the corners of the world to understand religion.’ So, when they come to you, he instructed you to be their well-wishers”
[Ibn Majah 249]
