Narrated Ibn `Abbas:that his aunt, Um Hufaid bint Al-Harith bin Hazn, presented to the Prophet (ﷺ) butter, dried yoghurt and mastigures. The Prophet (ﷺ) invited the people to those mastigures and they were eaten on his dining sheet, but the Prophet (ﷺ) did not eat of it, as if he disliked it. Nevertheless. if it was unlawful to eat that, the people would not have eaten it on the dining sheet of the Prophet (ﷺ) nor would he have ordered that they be eaten
