Sunan Ibn Majah, Chapter: The Book of the Sunnah

"We entered upon Hasan to inquire after him until we filled the house. He tucked up his legs, then he (Hasan) said: 'We entered upon Abu Hurairah to inquire after him until we filled the house. He (Abu Hurairah) tucked up his legs and said: "We entered upon the Messenger of Allah (saw) until we filled the house. He was lying on his side, but when he saw us he tucked up his legs then he said: 'After I am gone, there will come to you people seeking knowledge. Welcome them, greet them and teach them.'" (Maudu) A narrator said: By Allah! We came across some people who did not welcome us, greet us, nor teach us until we used to go to them, then they treated us rudely.
