No person should ask another person to stand at his place and then he should himself sit there, but he should simply say: Make room and accommodate. (Using translation from Muslim 2177b)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يُقِيمُ الرَّجُلُ الرَّجُلَ مِنْ مَقْعَدِهِ ثُمَّ يَجْلِسُ فِيهِ وَلَكِنْ تَفَسَّحُوا وَتَوَسَّعُوا
