Yahya related to me from Malik from Abu Nuaym that Wahb ibn Kaysan said, "The Messenger of Allah ﷺ was brought food while his stepson Umar ibn Salama was with him. The Messenger of Allah ﷺ said to him, 'Say "Bismillah," and eat what is in front of you.' "
قَالَ أُتِيَ رَسُولُ اللَّهِ ﷺ بِطَعَامٍ وَمَعَهُ رَبِيبُهُ عُمَرُ بْنُ أَبِي سَلَمَةَ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ سَمِّ اللَّهَ وَكُلْ مِمَّا يَلِيكَ
