Umm al-Fadl (Allah be pleased with her) is reported to have said that some people among the Companions of the Messenger of Allah ﷺ were in doubt about fasting on the day of 'Arafa and we were with him on that day. I (Umm al-Fadl) sent him a cup of milk and he was halting at 'Arafa, and he drank that.  

مسلم:١١٢٣d – وَحَدَّثَنِي هَارُونُ بْنُ سَعِيدٍ الأَيْلِيُّ حَدَّثَنَا ابْنُ وَهْبٍ أَخْبَرَنِي عَمْرٌو أَنَّ أَبَا النَّضْرِ حَدَّثَهُ أَنَّ عُمَيْرًا مَوْلَى ابْنِ عَبَّاسٍ ؓ حَدَّثَهُ

أَنَّهُ سَمِعَ أُمَّ الْفَضْلِ ؓ تَقُولُ شَكَّ نَاسٌ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ فِي صِيَامِ يَوْمِ عَرَفَةَ وَنَحْنُ بِهَا مَعَ رَسُولِ اللَّهِ ﷺ فَأَرْسَلْتُ إِلَيْهِ بِقَعْبٍ فِيهِ لَبَنٌ وَهُوَ بِعَرَفَةَ فَشَرِبَهُ

[Machine] He heard Umm al-Fadl saying, "People had doubts about fasting on the Day of Arafah, while we were with the Messenger of Allah ﷺ, so I sent him a container of milk and he drank it while he was in Arafah."  

الطبراني:٢١٥٩٧ – حَدَّثَنَا الْحُسَيْنُ بْنُ إِسْحَاقَ التُّسْتَرِيُّ ثنا حَرْمَلَةُ بْنُ يَحْيَى ثنا ابْنُ وَهْبٍ أَخْبَرَنِي عَمْرُو بْنُ الْحَارِثِ أَنَّ أَبَا النَّضْرِ حَدَّثَهُ أَنَّ عُمَيْرًا مَوْلَى ابْنِ عَبَّاسٍ حَدَّثَهُ

أَنَّهُ سَمِعَ أُمَّ الْفَضْلِ تَقُولُ «شَكَّ النَّاسُ فِي صِيَامِ يَوْمِ عَرَفَةَ وَنَحْنُ مَعَ رَسُولِ اللهِ ﷺ فَأَرْسَلْتُ إِلَيْهِ بِقَعْبٍ مِنْ لَبَنٍ وَهُوَ بِعَرَفَةَ فَشَرِبَهُ»
