Al-Adab Al-Mufrad · Book 46 · Hadith 1140
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.
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."
