When a man rises to give place for someone in a gathering, that person should not sit in it

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 صلى الله عليه وسلم أَنْ يُقِيمَ الرَّجُلَ مِنَ الْمَجْلِسِ ثُمَّ يَجْلِسُ فِيهِ‏.‏
