Ibn `Abbas said: Um Hufaid, Ibn `Abbas's aunt sent some dried yogurt (butter free), ghee (butter) and
a mastigar to the Prophet (ﷺ) as a gift. The Prophet (ﷺ) ate the dried yogurt and butter but left the mastigar
because he disliked it. Ibn `Abbas said, "The mastigar was eaten at the table of Allah's Messenger (ﷺ) and if
it had been illegal to eat, it could not have been eaten at the table of Allah's Messenger (ﷺ)."
