Hadith 17:274
Narrated to us Abd al-A’la, from Ma’mar, from al-Zuhri, from Salim, from Ibn Umar, that the Prophet (peace be upon him) said: "Let no one of you make his brother stand up from his sitting place, then sit in it." He said: And Ibn Umar, when a man would stand up for him from his sitting place, he would not sit in it.
حدثنا عبد الأعلى عن معمر عن الزهري عن سالم عن بن عمر أن النبي صلى الله عليه وسلم قال لا يقمن أحدكم أخاه من مجلسه ثم يجلس فيه قال وكان بن عمر إذا قام له الرجل من مجلسه لم يجلس فيه
