Hadith 46:5
Sahih (Al-Albani)
Ibn 'Umar reported that the Prophet, may Allah bless him and grant him peace, said, "None of you should make a man rise from his seat and then sit in it. Rather make room and spread out."
حَدَّثَنَا الْحُمَيْدِيُّ، قَالَ: حَدَّثَنَا ابْنُ عُيَيْنَةَ، قَالَ: حَدَّثَنَا عُبَيْدُ اللهِ بْنُ عُمَرَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ قَالَ: قَالَ النَّبِيُّ صلى الله عليه وسلم: لاَ يُقِيمَنَّ أَحَدُكُمُ الرَّجُلَ مِنْ مَجْلِسِهِ، ثُمَّ يَجْلِسُ فِيهِ، وَلَكِنْ تَفَسَّحُوا وَتَوَسَّعُوا
