Sahih al-Bukhari 70:62
Narrated Abu Mas`ud Al-Ansari:
There was a man called Abu Shu'aib, and he had a slave who was a butcher. He said (to his slave), "Prepare a meal to which I may invite Allah's Messenger (ﷺ) along with four other men." So he invited Allah's Messenger (ﷺ) and four other men, but another man followed them whereupon the Prophet (ﷺ) said, "You have invited me as one of five guests, but now another man has followed us. If you wish you can admit him, and if you wish you can refuse him." On that the host said, "But I admit him." Narrated Muhammad bin Isma`il: If guests are sitting at a dining table, they do not have the right to carry food from other tables to theirs, but they can pass on food from their own table to each other; otherwise they should leave it.

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنِ الأَعْمَشِ، عَنْ أَبِي وَائِلٍ، عَنْ أَبِي مَسْعُودٍ الأَنْصَارِيِّ، قَالَ كَانَ مِنَ الأَنْصَارِ رَجُلٌ يُقَالُ لَهُ أَبُو شُعَيْبٍ، وَكَانَ لَهُ غُلاَمٌ لَحَّامٌ فَقَالَ اصْنَعْ لِي طَعَامًا أَدْعُو رَسُولَ اللَّهِ صلى الله عليه وسلم خَامِسَ خَمْسَةٍ، فَدَعَا رَسُولَ اللَّهِ صلى الله عليه وسلم خَامِسَ خَمْسَةٍ، فَتَبِعَهُمْ رَجُلٌ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " إِنَّكَ دَعَوْتَنَا خَامِسَ خَمْسَةٍ وَهَذَا رَجُلٌ قَدْ تَبِعَنَا، فَإِنْ شِئْتَ أَذِنْتَ لَهُ، وَإِنْ شِئْتَ تَرَكْتَهُ ". قَالَ بَلْ أَذِنْتُ لَهُ. قَالَ مُحَمَّدُ بْنُ يُوسُفَ سَمِعْتُ مُحَمَّدَ بْنَ إِسْمَاعِيْلَ يَقُولُ إِذَا كَانَ الْقَوْمُ عَلَى الْمَائِدَةِ لَيْسَ لَهُمْ أَنْ يُنَاوِلُوا مِنْ مَائِدَةٍ إِلَى مَائِدَةٍ أُخْرَى وَلَكِنْ يُنَاوِلُ بَعْضُهُمْ بَعْضًا فِي تِلْكَ الْمَائِدَةِ أَوْ يَدَعُ
