EAT IN THE NAME OF ALLAH WITH YOUR RIGHT HAND H H 299 "Omar, the son of Umm Salah was in the care of the Prophet, praise and peace be upon him. He mentioned: 'When I ate, I would put my hand inside the bowl, then the Holy 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 his habit." R 299 Bukhari and Muslim with a chain up to Omar son of Abi Salamah who related this.
299- وعن أَبي حفص عمر بن أَبي سلمة عبد الله بن عبد الأسدِ ربيبِ رَسُول الله صلى الله عليه وآله وسلم ، قَالَ : كُنْتُ غلاَماً في حجر رَسُول الله صلى الله عليه وآله وسلم وَكَانَتْ يَدي تَطِيشُ في الصَّحْفَةِ ، فَقَالَ لي رَسُول الله صلى الله عليه وآله وسلم : "يَا غُلامُ ، سَمِّ الله تَعَالَى ، وَكُلْ بيَمِينكَ ، وَكُلْ مِمَّا يَلِيكَ" فَمَا زَالَتْ تِلْكَ طِعْمَتي بَعْدُ . مُتَّفَقٌ عَلَيهِ . " وَتَطِيشُ" : تدور في نواحِي الصحفة .
