باب تَحْرِيمِ إِقَامَةِ الإِنْسَانِ مِنْ مَوْضِعِهِ الْمُبَاحِ الَّذِي سَبَقَ إِلَيْهِ ‏‏
Sahih Muslim 2178

Jabir reported Allah's Apostle (may peace he upon him) as saying:

None amongst you should make his brother stand on Friday (during the congregational prayer) and then occupy his-place. but he should only say to him (Accommodate me).
وَحَدَّثَنَا سَلَمَةُ بْنُ شَبِيبٍ، حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ، حَدَّثَنَا مَعْقِلٌ، - وَهُوَ ابْنُ عُبَيْدِ اللَّهِ - عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ يُقِيمَنَّ أَحَدُكُمْ أَخَاهُ يَوْمَ الْجُمُعَةِ ثُمَّ لْيُخَالِفْ إِلَى مَقْعَدِهِ فَيَقْعُدَ فِيهِ وَلَكِنْ يَقُولُ افْسَحُوا ‏"‏ ‏.‏
