ON THE SUBJECT OF 100 TABLE MANNERS; HOW TO EAT H 735 "Omar, the son of Lady Umm Salamah, wife of the Prophet, may Allah be pleased with her, was in the care of the Prophet, praise and peace be upon him. Omar said, I used to put my hand inside the bowl when I ate, then the Prophet, praise and peace be upon him, told me 'to mention the Name of Allah and eat whatever was in front of me with my right hand'. From that time onward this became my eating habit". R 735 Bukhari and Muslim with a chain up to Omar son of Abi Salamah who related this.
