Narrated Ibn `Umar:
حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَبْدِ اللَّهِ ، قَالَ حَدَّثَنِي مَالِكٌ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ يُقِيمُ الرَّجُلُ الرَّجُلَ مِنْ مَجْلِسِهِ، ثُمَّ يَجْلِسُ فِيهِ " .
The Prophet (ﷺ) said, "A man should not make another man get up from his (the latter's) seat (in a gathering) in order to sit there.
