[Machine] We, the family of Muhammad ﷺ , used to see the crescent moon pass by us repeatedly. We would only kindle fire for food, which was dates and water. However, the people of the dwellings of the Ansar would send the people from each house with their bowls to the Messenger of Allah ﷺ , so he would have milk from it. This is mentioned in the authentic Hadith narrated by Hisham and others, from Urwah.  

قَدْ كُنَّا آلَ مُحَمَّدٍ ﷺ يَمُرُّ بِنَا الْهِلَالُ وَالْهِلَالُ وَالْهِلَالُ مَا نُوقِدُ بِنَارٍ لِطَعَامٍ إِلَّا أَنَّهُ التَّمْرُ وَالْمَاءُ إِلَّا أَنَّهُ حَوْلَنَا أَهْلُ دُورٍ مِنَ الْأَنْصَارِ فَيَبْعَثُ أَهْلُ كُلِّ دَارٍ بِغَرِيزَةِ شَاتِهِمْ إِلَى رَسُولِ اللهِ ﷺ فَكَانَ لِلنَّبِيِّ ﷺ مِنْ ذَلِكَ اللَّبَنُ أَخْرَجَاهُ فِي الصَّحِيحِ مِنْ حَدِيثِ هِشَامٍ وَغَيْرُهُ عَنْ عُرْوَةَ
