Musnad Ahmad 27:1911

'Abd al-Razzaq narrated to us, Ibn Jurayj informed us, I heard Nafi' saying: Ibn 'Umar said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Let no one of you make his brother stand up from his seat, then sit in it himself." I (Ibn Jurayj) said to him: "On Friday?" He said: "On Friday and other than it."
