Chapter: Eating from what is directly in front of one, and admonishing and correcting anyone who eats improperly.

740 – ʿUmar ibn Abī Salama (may Allah be pleased with him) reported: “I was a young boy in the care of the Messenger of Allah ﷺ, and my hand would wander all over the dish. The Messenger of Allah ﷺ said to me, ‘Young man, mention the name of Allah, eat with your right hand, and eat from what is in front of you.’” Agreed upon by al-Bukhārī and Muslim.
His statement “tatīshu” (with a short i on the tāʾ, followed by a yāʾ) means that the hand moved about and stretched toward the various sides of the serving dish.

741 – Salama ibn al-Akwaʿ (may Allah be pleased with him) narrated that a man once ate with his left hand in the presence of the Messenger of Allah ﷺ. The Prophet said, “Eat with your right hand.” The man replied, “I cannot.” The Prophet said, “May you never be able!” Nothing prevented him from complying except arrogance, and afterward he was unable to raise his right hand to his mouth. Narrated by Muslim.

[Commentary]
The author—may Allah have mercy on him—states in “The Book of Table Manners”: “Chapter: Eating from what is nearest to oneself and exhorting and disciplining the one who behaves improperly while eating.”
