It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that he said: It has been forbidden to eat the food of two people who are competing with each other in outdoing one another in feeding people (for show and fame). This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) forbade two kinds of eating: sitting and eating at a table on which wine is being drunk, and a man eating while lying on his stomach. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
