Muwatta Imam Malik Book of Hajj, Hadith 136

Yahya related to me from Malik from Ibn Shihab that the Messenger of Allah ﷺ sent Abdullah ibn Hudhayfa out on the days of Mina to circulate among the people to tell them those days were for eating and drinking and remembrance of Allah.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، أَنَّ رَسُولَ اللَّهِ ﷺ بَعَثَ عَبْدَ اللَّهِ بْنَ حُذَافَةَ أَيَّامَ مِنًى يَطُوفُ يَقُولُ إِنَّمَا هِيَ أَيَّامُ أَكْلٍ وَشُرْبٍ وَذِكْرِ اللَّهِ .
