I was a boy under the care of Messenger of Allah ﷺ and my hand used to go around the dish while I was eating. So Messenger of Allah ﷺ said to me, 'O boy! Mention the Name of Allah and eat with your right hand, and eat of the dish what is nearer to you." Since then I have applied those instructions when eating. (Using translation from Bukhārī 5376)   

سَمِعْتُ عُمَرَ بْنَ أَبِي سَلَمَةَ يَقُولُ كُنْتُ غُلَامًا فِي حِجْرِ رَسُولِ اللهِ ﷺ وَكَانَتْ يَدِي تَطِيشُ فِي الصَّحْفَةِ فَقَالَ لِي رَسُولُ اللهِ ﷺ «يَا غُلَامُ سَمِّ اللهَ وَكُلْ بِيَمِينِكَ وَكُلْ مِمَّا يَلِيكَ» خَالَفَهُ مَالِكُ بْنُ أَنَسٍ  

A meal was brought to Messenger of Allah ﷺ while his step-son, ʿUmar bin Abi Salama was with him. Messenger of Allah ﷺ said to him, "Mention the Name of Allah and eat of the dish what is nearer to you." (Using translation from Bukhārī 5378)   

أُتِيَ رَسُولُ اللهِ ﷺ بِطَعَامٍ وَمَعَهُ رَبِيبُهُ عُمَرُ بْنُ أَبِي سَلَمَةَ فَقَالَ لَهُ «سَمِّ اللهَ وَكُلْ مِمَّا يَلِيكَ» هَذَا أَوْلَى بِالصَّوَابِ
