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.”
