Chapter: The Prohibition Of Making A Man Get Up From A Place That He Reached First
(11)
باب تَحْرِيمِ إِقَامَةِ الإِنْسَانِ مِنْ مَوْضِعِهِ الْمُبَاحِ الَّذِي سَبَقَ إِلَيْهِ ‏‏
Sahih Muslim 2177 d

Ibn 'Umar reported Allah's Messenger (ﷺ) as saying:

None should make one'& brother stand and then sit at his place (and it was common with) Ibn Umar that when any person stood in the company (with a view to making room for him) he did not sit there.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ الأَعْلَى، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ يُقِيمَنَّ أَحَدُكُمْ أَخَاهُ ثُمَّ يَجْلِسُ فِي مَجْلِسِهِ ‏"‏ ‏.‏ وَكَانَ ابْنُ عُمَرَ إِذَا قَامَ لَهُ رَجُلٌ عَنْ مَجْلِسِهِ لَمْ يَجْلِسْ فِيهِ ‏.‏
