Ibn ʿAbbas said: Um Hufaid, Ibn ʿAbbas'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 ʿAbbas said, "The mastigar was eaten at the table of Messenger of Allah ﷺ and if it had been illegal to eat, it could not have been eaten at the table of Messenger of Allah ﷺ." (Using translation from Bukhārī 2575)
أَهْدَتْ أُمُّ حُفَيْدٍ خَالَةُ ابْنِ عَبَّاسٍ إِلَى رَسُولِ اللهِ ﷺ أَقِطًا وَسَمْنًا وَأَضُبًّا فَأَكَلَ رَسُولُ اللهِ ﷺ مِنَ الْأَقِطِ وَالسَّمْنِ وَتَرَكَ الْأَضُبَّ تَقَذُّرًا قَالَ ابْنُ عَبَّاسٍ فَأُكِلَ عَلَى مَائِدَةِ رَسُولِ اللهِ ﷺ وَلَوْ كَانَ حَرَامًا مَا أُكِلَ عَلَى مَائِدَتِهِ
