Narrated 'Umar bin Abu Salamah (RA):

Allah's Messenger (ﷺ) said to me, "Dear child, mention Allah's Name, eat with your right hand, and eat from what is next to you." [Agreed upon].

وَعَنْ عُمَرَ بْنِ أَبِي سَلَمَةَ ‏- رضى الله عنه ‏- قَالَ : قَالَ اَلنَّبِيُّ ‏- صلى الله عليه وسلم ‏-{ يَا غُلَامُ ! سَمِّ اَللَّهَ , وَكُلْ بِيَمِينِكَ , وَكُلْ مِمَّا يَلِيكَ } مُتَّفَقٌ عَلَيْهِ [1]‏ .‏
