What did Allah's Apostle (saw) instruct `Umar bin Abi Salama to do before eating the meal brought to them?
 Narrated Wahb bin Kaisan Abi Nu'aim:                     A meal was brought to Allah's Apostle while his step-son, `Umar bin Abi Salama was with him. Allah's Apostle said to him, "Mention the Name of Allah and eat of the dish what is nearer to you."
