Kuraib, the freed slave of Ibn 'Abbas (Allah be pleased with him), reported from Maimuna, the wife of the Apostle of Allah ﷺ, that people had doubt about the fasting of Messenger of Allah ﷺ on the day of 'Arafa. Maimuna sent him a cup of milk and he was halting at a place and he drank it and the people were seeing him.

وَحَدَّثَنِي هَارُونُ بْنُ سَعِيدٍ الأَيْلِيُّ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي عَمْرٌو، عَنْ بُكَيْرِ بْنِ، الأَشَجِّ عَنْ كُرَيْبٍ، مَوْلَى ابْنِ عَبَّاسٍ - رضى الله عنهما - عَنْ مَيْمُونَةَ، زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ إِنَّ النَّاسَ شَكُّوا فِي صِيَامِ رَسُولِ اللَّهِ ﷺ يَوْمَ عَرَفَةَ فَأَرْسَلَتْ إِلَيْهِ مَيْمُونَةُ بِحِلاَبِ اللَّبَنِ وَهُوَ وَاقِفٌ فِي الْمَوْقِفِ فَشَرِبَ مِنْهُ وَالنَّاسُ يَنْظُرُونَ إِلَيْهِ .
