It was narrated from Ibn ‘Umar that the Messenger of Allah ﷺ said:
“When a meal is served, a man should not stand up until it is removed, and he should not take his hand away, even if he is full, until the people have finished. And let him continue eating.* For a man may make his companion shy, causing him to withhold his hand, and perhaps he has a need for the food.”

حَدَّثَنَا مُحَمَّدُ بْنُ خَلَفٍ الْعَسْقَلاَنِيُّ، حَدَّثَنَا عُبَيْدُ اللَّهِ، أَنْبَأَنَا عَبْدُ الأَعْلَى، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ ﷺ ـ " إِذَا وُضِعَتِ الْمَائِدَةُ فَلاَ يَقُومُ رَجُلٌ حَتَّى تُرْفَعَ الْمَائِدَةُ وَلاَ يَرْفَعُ يَدَهُ وَإِنْ شَبِعَ حَتَّى يَفْرُغَ الْقَوْمُ وَلْيُعْذِرْ فَإِنَّ الرَّجُلَ يُخْجِلُ جَلِيسَهُ فَيَقْبِضُ يَدَهُ وَعَسَى أَنْ يَكُونَ لَهُ فِي الطَّعَامِ حَاجَةٌ " .
