سنن ابن ماجه

It was narrated that Ibn ‘Umar said that ‘Umar entered upon him when he was eating, and he made room for him in the middle of the gathering. He said: Bismillah, then he took a morsel and ate it, then a second. Then he said: “I notice some fat in the food but it is not the fat of the meat.” ‘Abdullah said: “O Commander of the Believers! I went out to the marketplace looking for some fatty meat (bones with plenty of meat on them) to buy, but it was expensive, so I bought some lean meat (bones with not much meat on them) for a Dirham, and added a Dirham’s worth of ghee. I wanted my family to go through it bone by bone.” ‘Umar said: “The Messenger of Allah (ﷺ) never had these two things together; he would eat one and give the other in charity.”
