Muwatta Malik 1706
The Description of the Prophet (ﷺ)
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي نُعَيْمٍ، وَهْبِ بْنِ كَيْسَانَ قَالَ أُتِيَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِطَعَامٍ وَمَعَهُ رَبِيبُهُ عُمَرُ بْنُ أَبِي سَلَمَةَ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم سَمِّ اللَّهَ وَكُلْ مِمَّا يَلِيكَ .
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.' "
