Mishkat al-Masabih #4082

Ibn ‘Umar reported God’s messenger as saying, "When the cloth is set down a man must not get up till it is removed, nor must he withdraw his hand even if he has had enough till the people have finished, but if he does he should make his excuse, for that embarrasses his companion and he does not stretch out his hand although he may perhaps require the food." Ibn Majah and Baihaqi, in Shu'ab al-iman, transmitted it.
