Sahih al-Bukhari 5378

ʿAbdullah ibn Yusuf informed us: Malik informed us, from Wahb ibn Kaysan Abu Nuʿaym, who said: Food was brought to the Messenger of God, peace and blessings be upon him, while his stepson ʿUmar ibn Abi Salamah was with him. He said, “Mention the name of God, and eat from what is nearest to you.”
