AbuUmayr reported on the authority of some of his paternal uncles who were Companions of the Prophet ﷺ: Some men came riding to the Prophet ﷺ and testified that they had sighted the new moon the previous day. He (the Holy Prophet), therefore, commanded the people to break the fast and to go out to their place of prayer in the morning.  

عَنْ عُمُومَةٍ لَهُ مِنْ أَصْحَابِ النَّبِيِّ ﷺ أَنَّ رَكْبًا جَاءُوا إِلَى النَّبِيِّ ﷺ يَشْهَدُونَ أَنَّهُمْ رَأَوُا الْهِلاَلَ بِالأَمْسِ فَأَمَرَهُمْ أَنْ يُفْطِرُوا وَإِذَا أَصْبَحُوا أَنْ يَغْدُوا إِلَى مُصَلاَّهُمْ  

I used to go to the place of prayer on the day of the breaking of the fast, and on the day of sacrifice along with the Companions of the Messenger of Allah ﷺ. We would walk through a valley known as Batn Bathan till we came to the place of prayer. Then we would pray along with the Messenger of Allah ﷺ and return through Batn Bathan to our house.  

كُنْتُ أَغْدُو مَعَ أَصْحَابِ رَسُولِ اللَّهِ ﷺ إِلَى الْمُصَلَّى يَوْمَ الْفِطْرِ وَيَوْمَ الأَضْحَى فَنَسْلُكُ بَطْنَ بَطْحَانَ حَتَّى نَأْتِيَ الْمُصَلَّى فَنُصَلِّيَ مَعَ رَسُولِ اللَّهِ ﷺ ثُمَّ نَرْجِعُ مِنْ بَطْنِ بَطْحَانَ إِلَى بُيُوتِنَا
