When a man rises to give place for someone in a gathering, that person should not sit in it
بَابُ إِذَا قَامَ لَهُ رَجُلٌ مِنْ مَجْلِسِهِ لَمْ يَقْعُدْ فِيهِ

Ibn 'Umar said, "The Prophet ﷺ forbade anyone forcing a man to rise from his seat so that someone else could sit in his place."
حَدَّثَنَا قَبِيصَةُ، قَالَ: حَدَّثَنَا سُفْيَانُ، عَنْ عُبَيْدِ اللهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ قَالَ: نَهَى النَّبِيُّ ﷺ أَنْ يُقِيمَ الرَّجُلَ مِنَ الْمَجْلِسِ ثُمَّ يَجْلِسُ فِيهِ.
