Muslim Manners

‘Umar bin Abu Salamah (May Allah be pleased with them) reported:

I was a boy under the care of Messenger of Allah (may Allah’s peace be upon him), and as my hand used to wander around in the dish, he (may Allah’s peace be upon him) said to me once:

“Mention Allah’s Name (i.e., say Bismillah), eat with your right hand, and eat from what is in front of you.”

[Al-Bukhari and Muslim].

Commentary from Riayad-us-Saliheen:  ‘Umar bin Abu Salamah (May Allah be pleased with them) had learnt table manners from Messenger of Allah (may Allah’s peace be upon him) who was his stepfather and guardian. Hence, everybody is morally bound to teach his wards or children good manners.
[Riyad-us-Saliheen; Chapter 104, #740.  Dar-us-Salaam]
