IBNMAJAH 3267:
from Wahb b. Kaysān Samiʿah from ʿUmar b. Abū Salamah —
“I was a boy in the care of the Prophet ﷺ and my hand used to wander all over the plate. He said to me: ‘O boy! Say the Name of Allah, eat with your right hand, and eat from what is in front of you.’”
ابن ماجة ٣٢٦٧:
عن وهب بن كيسان سمعه عن عمر بن ابو سلمه —
كُنْتُ غُلاَمًا فِي حِجْرِ النَّبِيِّ ﷺ وَكَانَتْ يَدِي تَطِيشُ فِي الصَّحْفَةِ فَقَالَ لِي يَا غُلاَمُ سَمِّ اللَّهَ وَكُلْ بِيَمِينِكَ وَكُلْ مِمَّا يَلِيكَ
