bayhaqi:8196Abū al-Ḥasan ʿAlī b. Muḥammad al-Muqriʾ > al-Ḥasan b. Muḥammad b. Isḥāq > Yūsuf b. Yaʿqūb al-Qāḍī > Abū al-Rabīʿ > Abū ʿAwānah > Abū Bishr > Abū ʿUmayr b. Anas

[Machine] From a general companion of the Prophet ﷺ , it is reported that the people of Madinah used to observe fasting on the last day of Ramadan during the time of the Prophet ﷺ . A group arrived at the end of the day and testified before the Messenger of Allah ﷺ that they had seen the new crescent yesterday. The Messenger of Allah ﷺ then ordered the people to break their fast and proceed to their prayer place, and so they did.  

البيهقي:٨١٩٦أَخْبَرَنَا أَبُو الْحَسَنِ عَلِيُّ بْنُ مُحَمَّدٍ الْمُقْرِئُ أنبأ الْحَسَنُ بْنُ مُحَمَّدِ بْنِ إِسْحَاقَ ثنا يُوسُفُ بْنُ يَعْقُوبَ الْقَاضِي ثنا أَبُو الرَّبِيعِ ثنا أَبُو عَوَانَةَ عَنْ أَبِي بِشْرٍ عَنْ أَبِي عُمَيْرِ بْنِ أَنَسٍ

عَنْ عُمُومَةٍ لَهُ مِنْ أَصْحَابِ النَّبِيِّ ﷺ قَالَ أَصْبَحَ أَهْلُ الْمَدِينَةِ صِيَامًا فِي آخِرِ يَوْمٍ مِنْ رَمَضَانَ عَلَى عَهْدِ النَّبِيِّ ﷺ فَقَدِمَ رَكْبٌ مِنْ آخِرِ النَّهَارِ فَشَهِدُوا عِنْدَ رَسُولِ اللهِ ﷺ أَنَّهُمْ رَأَوَا الْهِلَالَ بِالْأَمْسِ فَأَمَرَ رَسُولُ اللهِ ﷺ النَّاسَ أَنْ يُفْطِرُوا وَيَغْدُوا إِلَى مُصَلَّاهُمْ وَكَذَلِكَ  

رَوَاهُ بِمَعْنَاهُ شُعْبَةُ وَهُشَيْمُ بْنُ بَشِيرٍ عَنْ أَبِي بِشْرٍ جَعْفَرِ بْنِ أَبِي وَحْشِيَّةَ وَهُوَ إِسْنَادٌ حَسَنٌ وَأَبُو عُمَيْرٍ رَوَاهُ عَنْ عُمُومَةٍ لَهُ مِنْ أَصْحَابِ النَّبِيِّ ﷺ وَأَصْحَابُ النَّبِيِّ ﷺ كُلُّهُمْ ثِقَاتٌ فَسَوَاءٌ سُمُّوا أَوْ لَمْ يُسَمَّوْا
